According to Gartner Inc., the largest share of the worldwide PC market is held by Hewlett-Packard with 19.8%. Suppose that a market researcher believes that Hewlett-Packard holds a higher share of the market in Ontario. To verify this theory, he randomly selects 427 people who purchased a personal computer in the last month in Ontario. Ninety of these purchases were Hewlett-Packard computers. Using a 1% level of significance, test the market researcher’s theory. If the market share is really 0.22 in Ontario, what is the probability of making a Type II error?

Answers

Answer 1

The probability of making a Type II error (i.e., failing to reject the null hypothesis when the true proportion is actually 0.25) is 0.0104.

What is error?

An error is the difference between a true value and an estimated or approximate representation of that value in applied mathematics. A truncation error occurs when an infinite series is ignored for all but a small number of terms. power 1 P (type II error)

In this case, if the market share in Ontario is actually 0.22, the probability that 90 or fewer Hewlett-Packard computers will be observed out of 427 randomly selected purchases is quite small. The probability of 90 or fewer successes for a binomial distribution with n = 427 and p = 0.22 is approximately 0.219, or 21.9%.

Therefore, the probability of making a Type II error (ie, failing to reject the null hypothesis incorrectly) is approximately 78.1%. This means that if Hewlett-Packard's market share in Ontario is actually 0.22, it is still relatively high. the possibility that the market researcher's test fails to detect this difference and incorrectly concludes that their market share does not exceed 0.198.

Therefore, the probability of a Type II error (ie, failing to reject the null hypothesis when the true proportion is actually 0.25) is 0.0104.

Answers

When creating a control chart, there are several main issues that need to be addressed. These include identifying the process that needs to be monitored and controlled, determining the appropriate data collection methods, selecting the appropriate chart type, setting control limits, and establishing a system for interpreting and responding to chart results.

Firstly, it is important to clearly define the process being monitored and controlled, and to ensure that the data collected accurately reflects the process performance. Secondly, data collection methods need to be established, including how frequently data will be collected and who will be responsible for collecting it.
Thirdly, the appropriate type of control chart needs to be selected based on the type of data being collected and the nature of the process being monitored. This could include variable charts, attribute charts, or time-weighted charts.
Fourthly, control limits need to be established based on the expected variation in the process, and these limits need to be communicated to those responsible for the process. Finally, a system for interpreting and responding to chart results needs to be put in place, including a plan for addressing any out-of-control signals or trends in the data.

In summary, the main issues to address in creating a control chart include process identification, data collection methods, chart selection, control limit setting, and interpretation and response systems.

finding the slope for (-2,-5) (0,5)

Answers

Answer:

The slope is 5.

Step-by-step explanation:

Pre-Solving

We are given the points (-2, -5) and (0,5).

We want to find the slope between these 2 points.

The slope (m) is written with the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points.

Solving

Let's label the values of the points to avoid any confusion and mistakes when calculating.

[tex]x_1=-2\\y_1=-5\\x_2=0\\y_2=5[/tex]

Now, substitute into the formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{5--5}{0--2}[/tex]

This can be simplified to:

[tex]m = \frac{5+5}{0+2}[/tex]

Add the values together.

[tex]m = \frac{10}{2}[/tex]

Answers

West Virginia is needed to estimate the true proportion of children living in poverty within 3% with 95% confidence

To estimate the required sample size, we can use the formula:

n = (Z^2 * p * (1-p)) / E^2

where:

Z = the Z-score associated with the desired level of confidence (95% confidence corresponds to a Z-score of 1.96)

p = the estimated proportion of the population with the characteristic of interest (in this case, the estimated proportion of children under age 6 living in poverty in West Virginia, which is 0.3)

E = the desired margin of error (in this case, 0.03)

Substituting the given values, we get:

n = (1.96^2 * 0.3 * (1-0.3)) / 0.03^2

Simplifying:

n = 601.78

Rounding up to the nearest whole number, we get:

n = 602

Therefore, a sample of at least 602 children under age 6 from West Virginia is needed to estimate the true proportion of children living in poverty within 3% with 95% confidence.

Answers

If P(A) = 0.80, P(B) = 0.65, and P(A È B) = 0.78, then P(B½A) =the answer is (a) 0.9750. By the formula for conditional probability

To find P(B|A), we can use the formula for conditional probability: P(B|A) = P(A ∩ B) / P(A). We know P(A) = 0.80, but we need to find P(A ∩ B).

We can use the formula for the union of two events: P(A ∪ B) = P(A) + P(B) - P(A ∩ B). We are given P(A ∪ B) = 0.78 and P(B) = 0.65.

Plugging in the values, we get:

0.78 = 0.80 + 0.65 - P(A ∩ B)

Now, solve for P(A ∩ B):

P(A ∩ B) = 0.80 + 0.65 - 0.78
P(A ∩ B) = 0.67

Now we can find P(B|A):

P(B|A) = P(A ∩ B) / P(A)
P(B|A) = 0.67 / 0.80
P(B|A) = 0.8375

20) Using Fundamental Theorem of Arithmetic, show that any positive integer n can be written as ab2 where a is a square-free number. (An integer a is called square-free if it is not divisible by a square of a prime number.)

Answers

C is a square-free number, and we have expressed n as the product of a square-free number and the square of primes in B, as desired:

[tex]n = ab^2[/tex], where a is square-free and b = q1 * q2 * ... * qm.

Let's start by applying the Fundamental Theorem of Arithmetic to any positive integer n. According to the theorem, we can express n as a product of prime powers:

[tex]n = p1^a1 * p2^a2 * ... * pk^ak[/tex]

where p1, p2, ..., pk are distinct prime numbers and a1, a2, ..., ak are positive integers.

Now, let's separate the primes into two groups: those that appear with an even exponent and those that appear with an odd exponent:

[tex]n = (p1^a1 * p2^a2 * ... * pk^ak/2) * (p1^a1/2 * p2^a2/2 * ... * pk^ak/2)[/tex]

Let's call the first group of primes A and the second group B. Notice that B consists of squares of primes, and thus any prime power in B can be written as the square of some other prime. Let's call these primes q1, q2, ..., qm.

So we can express B as:

[tex]B = q1^2 * q2^2 * ... * qm^2[/tex]

Let's now combine A and B, and call their product C:

C = A * B

Then we have:

[tex]n = C * (q1^2 * q2^2 * ... * qm^2)[/tex]

But notice that C has no square factors, because all the primes in B have an even exponent. Therefore, C is a square-free number, and we have expressed n as the product of a square-free number and the square of primes in B, as desired:

Answers

A minimum sample size of 601 voters is needed to estimate the population proportion of voters who would vote for the incumbent governor with a margin of error of 0.08 or less at a 95% confidence level.

To determine the minimum sample size needed to estimate the population proportion with a margin of error of 0.08 or less at 95% confidence, we need to use a formula called the sample size formula. The formula is as follows:

n = (Z² × p × q) / E

Where n is the sample size, Z is the z-score corresponding to the confidence level (1.96 for 95% confidence level), p is the estimated proportion of voters who would vote for the incumbent governor, q is the complement of p (1-p), and E is the desired margin of error (0.08).

Assuming we do not have any prior information about the proportion of voters who would vote for the incumbent governor, we can use a conservative estimate of 0.5 for p and q. Substituting the values into the formula, we get:

n = (1.96² × 0.5 × 0.5) / 0.08²
n = 600.25

The general solution of the given differential equation is:
y = (r^(1/2)) * (1 + Ce^(2r^(1/2))) or y = (r^(1/2)) * (-1 + Ce^(2r^(1/2)))

To find the general solution of r = y^2 - 1 dr, we need to separate the variables and integrate both sides. We can start by rearranging the equation as:
dr/(y^2 - 1) = dy/r

Now, we can integrate both sides. On the left side, we can use partial fractions to make the integration easier. We can write:
dr/(y^2 - 1) = [1/(2*(y-1))] - [1/(2*(y+1))] dy

Integrating both sides, we get:
1/2 * ln|y-1| - 1/2 * ln|y+1| = ln|r| + C
where C is the constant of integration.

We can simplify this as:
ln|(y-1)/sqrt(r)| - ln|(y+1)/sqrt(r)| = 2C

Using logarithmic properties, we can simplify further as:
ln|[(y-1)/sqrt(r)] / [(y+1)/sqrt(r)]| = 2C
ln|[(y-1)/(y+1)]| = 2C

Exponentiating both sides, we get:
|[(y-1)/(y+1)]| = e^(2C)

Taking the positive and negative cases separately, we get:
(y-1)/(y+1) = e^(2C)

or
(y-1)/(y+1) = -e^(2C)

Solving for y in each case, we get the general solution as:

y = (r^(1/2)) * (1 + Ce^(2r^(1/2))) or y = (r^(1/2)) * (-1 + Ce^(2r^(1/2)))

where C is the constant of integration. This is the general solution of the given differential equation.

You spin the spinner and flip a coin. Find the probability of the compound event is not spinning 5

Answers

The probability of the compound event of spinning a 5 and flipping heads is 1/12.

Assuming that the spinner is fair and each outcome is equally likely, the probability of spinning a 5 is:

P(spinning 5) = number of ways to get 5 / total number of outcomes

P(spinning 5) = 1 / 6

Now, assuming that the coin is fair and has an equal probability of landing on heads or tails, the probability of flipping heads is:

P(flipping heads) = number of ways to get heads / total number of outcomes

P(flipping heads) = 1 / 2

To find the probability of the compound event of spinning 5 and flipping heads, we multiply the probability of spinning 5 by the probability of flipping heads:

P(spinning 5 and flipping heads) = P(spinning 5) x P(flipping heads)

P(spinning 5 and flipping heads) = (1/6) x (1/2)

P(spinning 5 and flipping heads) = 1/12.

Let X be a continuous random variable symmetric about Y.
Let Z = 1 if X > Y OR
Z = 0 if X <= Y.
Find the covariance of |X| and Z.

Answers

However, since |X| and Z are not directly dependent on each other, their covariance will be 0. So, Cov(|X|, Z) = 0.

To find the covariance of |X| and Z, first let's understand the terms and the relationship between them.

Since X is a continuous random variable symmetric about Y, the probability distribution of X is symmetric around Y.

Now, Z is a binary random variable that takes the value 1 if X > Y, and 0 if X <= Y. Now, let's find the covariance:

Cov(|X|, Z) = E[(|X| - E[|X|])(Z - E[Z])]

Since X is symmetric about Y, we know that E[|X|] = E[X] (due to symmetry).

To find E[Z], we can observe that: E[Z] = P(X > Y) = 0.5 (As the distribution is symmetric about Y, the probability of X being greater than Y is 0.5)

Now, let's find E[(|X| - E[X])(Z - 0.5)]: E[(|X| - E[X])(Z - 0.5)] = ∫∫(|x| - E[X])(z - 0.5)f(x,z) dx dz

However, since |X| and Z are not directly dependent on each other, their covariance will be 0. So, Cov(|X|, Z) = 0.

Step-by-step explanation:

for an arbitrary population p, how many carts should the amusement park put out and what should they set their pretzel price to in order to maximize their profit? (answers may or may not be a function of p)

Answers

The optimal number of carts and pretzel price will depend on the size of the population and the competitive landscape. The park should conduct market research to determine the ideal price point and number of carts for their specific market.

To determine how many carts the amusement park should put out and what they should set their pretzel price to in order to maximize their profit for an arbitrary population p, several factors need to be considered.

Firstly, the demand for pretzels will depend on the size of the population p. If p is large, the park should put out more carts to meet the demand. However, if p is small, fewer carts would be sufficient.

Secondly, the price of the pretzels will also affect demand. If the price is too high, people may choose to buy other snacks or not purchase anything at all. On the other hand, if the price is too low, the park may not be able to cover their costs and make a profit. Therefore, the park should set the pretzel price to a level that is competitive with other snacks but still allows for a reasonable profit margin.

find the equation of the line that is purpendicular to y= -2/3x and contains the point (4,-8)

Answers

Answer:

y = 3/2x-14

Step-by-step explanation:

      The given line is y=-2/3x. So, the slope of the given line is -2/3.

Now, we have to find the perpendicular line to y= -2/3x passing through the point (4,-8).

       The product of two perpendicular lines is -1.

m1.m2 = -1.

-2/3.m2= -1

m2 = 3/2

        Now, we need to find the equation of the line passing through the point (4,-8) with slope 3/2.

The equation of slope-point form is (y-y1) = m(x-x1)

        y-(-8) = 3/2 (x-4)

        y+8 = 3/2x -6

Now, we have to add 6 on both sides.

        y + 8 + 6 = 3/2x - 6 + 6.

        y + 14 = 3/2x

        y = 3/2x - 14.

However, the group was not going to pass up such an amazing discovery.During the site excavation, the paleontologists found dozens of gravesites. Some of them held skeletal remains and potsherds with wavy lines etched in them. The scientists named this group the Kiffians.

The graves also contained tools and beads made from stones or bones, as well as refuse heaps containing the bones of the animals the people living in the area had consumed. Some of the graves didn't contain any pottery so it was a mystery which group they belonged to. It was also not known when these people lived in the desert or how they survived.The carbon-14 dating revealed that the Kiffians lived in the area around 9,700 years ago, and then the area was abandoned until the Tenerians lived in the area 7,000 years ago.
