sixty percent of 800 students in a business statistics class are female. if you want to make probability estimates of the sample proportion of female students without applying the finite population correction factor, what minimal sample size of the random sample should be used?

Answers

Answer 1

Sixty percent of 800 students in a business statistics class are female. if you want to make probability estimates of the sample proportion of female students without applying the finite population correction factor, 368 is the minimal sample size of the random sample should be used

The appropriate sample size for probability estimates of the sample proportion of female students in the business statistics class is determined by the margin of error (m) and the level of confidence (Z).

The formula for sample size calculation is as follows:

N = [tex](Z^2\times p \times q) / m^2[/tex]

where

N is the sample size

Z is the z-score that corresponds to the level of confidence

p is the estimated proportion of female students

q is 1 - p (proportion of male students)m is the margin of error.

Since we don't have any margin of error, we can assume it to be a standard value of 5%. And a z-score of 1.96 is appropriate for a 95% level of confidence.

As a result, the sample size for estimating the sample proportion of female students in the business statistics class is given by

N = [tex](1.96^2\times0.60\times0.40) / (0.05^2)[/tex]

N = 368 students

the extent to which a sample over or under represents characteristics of the population is known as:

Answers

The extent to which a sample over or under represents characteristics of the population is known as sampling error.

Sampling error is the difference between the characteristics of a sample and the characteristics of the population from which it is drawn. Sampling error occurs when a sample does not accurately represent a population due to the selection of individuals. It is measured as the difference between a sample statistic and the corresponding population parameter. For example, if a sample of 100 people is taken from a population of 1,000 people, the sample might not accurately reflect the population as a whole due to random selection.

Sampling error is an important consideration in survey research, as it can have an effect on the accuracy of the results. Sampling error can be reduced by using larger sample sizes or by using more representative sampling methods.

Answers

The equation of an exponential decay function with a range of (-∞,10), vertical shrink of 3/4, and vertical shift up 10 units is f(x) = 10 - (3/4)^x.

An exponential decay function can be written as f(x) = ab^x where b is the base of the exponential function and a is the initial value. If b is between 0 and 1, the function will exhibit exponential decay. Since we need a vertical shrink of 3/4, we can set b = 3/4.

We also need a vertical shift of 10 units, so we add 10 to the function. The resulting function is: f(x) = 10 - (3/4)^x. Therefore, the equation of an exponential decay function with a range of (-∞,10), vertical shrink of 3/4, and vertical shift up 10 units is f(x) = 10 - (3/4)^x.

to meet the required weight specification, a total of 30 yards of material must be used for each frame. what is the optimal solution? if ati purchase the professional grade for $8 per yard will optimal solution change?

Answers

The optimal solution would be to use $240 worth of professional grade material for each frame.

Describe Optimal Solution?

An optimal solution is a solution that provides the best possible outcome for a problem or situation, given a set of constraints or requirements. In mathematical optimization, an optimal solution is the solution that maximizes or minimizes an objective function while satisfying a set of constraints.

In other words, an optimal solution is the solution that is most efficient, effective, or desirable according to a certain set of criteria. It is the solution that achieves the best possible outcome, given the available resources and limitations.

To find the optimal solution, we need more information about the specific weight specification and the cost of different types of materials.

However, if we assume that there is only one type of material available, and that it costs $x per yard, we can set up an equation to find the optimal solution:

30x = cost per frame

If the professional grade material costs $8 per yard, then the equation becomes:

30(8) = $240 per frame

So, the optimal solution would be to use $240 worth of professional grade material for each frame, assuming that it meets the weight specification. If the weight specification requires a different amount of material, or if there are other materials available at different prices, the optimal solution would be different.

a die is continuously rolled 104 104 times. what is the probability that the total sum of all rolls does not exceed 375 375 ?

Answers

The probability that the total sum of all rolls does not exceed 375 is approximately 0.7165

Assuming the die is a fair six-sided die, the possible outcomes for each roll are numbers 1 through 6, each with a probability of 1/6.

Let X be the total sum of all rolls. Then X follows a discrete uniform distribution with parameters n = 104 (number of rolls) and a = 1 (minimum value of each roll). The expected value of X is:

E(X) = n × (a + b) / 2 = 104 × (1 + 6) / 2 = 365

The variance of X is

Var(X) = n × (b - a + 1)^2 / 12 = 104 × 6^2 / 12 = 312

The standard deviation of X is

SD(X) = sqrt(Var(X)) = sqrt(312) = 17.67

To calculate the probability that the total sum of all rolls does not exceed 375, we need to calculate the cumulative distribution function (CDF) of X and evaluate it at 375

P(X <= 375) = F(375)

where F(x) = P(X <= x) is the CDF of X.

Using the normal approximation to the binomial distribution, we can approximate X as a normal distribution with mean E(X) = 365 and standard deviation SD(X) = 17.67

Z = (X - E(X)) / SD(X)

Z follows a standard normal distribution with mean 0 and standard deviation 1.

P(X <= 375) = P(Z <= (375 - E(X)) / SD(X))

= P(Z <= (375 - 365) / 17.67)

= P(Z <= 0.566)

Using a standard normal distribution table or a calculator, we can find that P(Z <= 0.566) is approximately 0.7165.

 Find the median, which is the middle number in the data set
 Divide the data set into two halves and find the median of each half
 The median of the lower half is the lower quartile (Q1) and the median of the upper half is the upper quartile (Q3)
 Subtract the lower quartile from the upper quartile to find the interquartile range (IQR)

how far will 560J raise a block weighing 8 N

Answers

a force of 560J can raise a block weighing 8 N to a height of 70 meters. It's important to note that this calculation assumes no energy is lost due to friction or other factors, so in reality, the block may not reach exactly 70 meters.

How to calculate work?

To calculate the height to which a block weighing 8 N can be raised by a force of 560J, we need to use the formula for work done:

Work (W) = force (F) x distance (d) x cos(theta)

where theta is the angle between the force and the displacement. In this case, the force is the weight of the block (8 N), the distance is the height the block is raised (h), and theta is 0 degrees because the force is acting vertically upward and the displacement is in the same direction.

So, we can rearrange the formula to solve for the height (h):

h = W / (F x cos(theta))

Substituting the values we have, we get:

h = 560 J / (8 N x cos(0 degrees))

Since the cosine of 0 degrees is 1, we can simplify to:

h = 560 J / 8 N

h = 70 meters

Therefore, a force of 560J can raise a block weighing 8 N to a height of 70 meters. It's important to note that this calculation assumes no energy is lost due to friction or other factors, so in reality, the block may not reach exactly 70 meters.

Answers

Mark needs to invest 5572.24 hours (rounded to one decimal place) of study time in order to achieve an A letter grade in this course.

To determine the estimated minimum number of hours Mark should study, we need to solve for the number of hours such that his predicted score, given by the regression equation from part (b), is at least 90.

The regression equation is as follows: Predicted score = 48.74 + 0.00726(number of hours studied)

Setting the predicted score equal to 90 and solving for the number of hours studied gives:90 = 48.74 + 0.00726 (number of hours studied)

Solving for the number of hours studied gives: number of hours studied = (90 - 48.74)/0.00726= 5572.24

a) The degree of freedom for a sample size 25 is equals to the 24 and the critical value t* for 80% confidence interval and degree of freedom 24 is equals to 1.318.

b) The degree of freedom for a sample size 55 is equals to the 54 and the critical value t* for 98% confidence interval and degree of freedom 54 is equals to 2.403.

The t-distribution has a bell-shaped density curve but has more variance (spread) than a normal bell curve.

Degrees of freedom: The degrees of freedom of a t-distribution is represented by n−1 for a sample of size n.critical value: The critical t-value for a confidence level c and sample size n is obtained by following below steps,

Step 1: First express the confidence level as a number (in decimal) c with 0<c<1.

Step 2: Determine the significance level, denoted

α, by α = 1 − c.

Step 3: Use the t-distribution table to obtain the t-score (critical value) tα/2 where (i) the α is from Step 2 and (ii) the degrees of freedom equals n−1, where n is the sample size.

a) 80% of confidence interval and observation of

Sample size, n = 25

From above definition, degree of freedom= n - 1 = 25 - 1 = 24 and c = 80%

= 0.80

Significance level, α = 1- c = 1 - 0.80 = 0.20

and α/2 = 0.10 then use the t-table the critical t-value for this 80% confidence interval, t₀.₁₀ = 1.711.

b) 98% confidence interval with 55 observations. So, Sample size, n = 55

degree of freedom = n - 1 = 55 - 1 = 54,

c = 98% = 0.98

Significance level, α = 1-0.98 = 0.02

and α/2 = 0.01, then use the t-table the critical t-value for this 98% confidence interval, t₀.₀₁ = 2.669

Hence required value is 2.669.

suppose 6.0 mol pf h2 reacted with suffient nitrogen (n2). how many moles of ammonia would be produced

Answers

Thus, 4.0 moles of NH3 would be produced when 6.0 moles of H2 react with sufficient N2.

Suppose 6.0 mol of H2 reacts with sufficient N2 to produce ammonia, NH3. We can determine the number of moles of NH3 produced using stoichiometry.The balanced chemical equation for the reaction is:[tex]3H2(g) + N2(g) → 2NH3(g)[/tex]

From the equation, we can see that 3 moles of H2 react with 1 mole of N2 to produce 2 moles of NH3.

Therefore, using the mole ratio from the balanced equation, we can calculate the number of moles of NH3 that would be produced when 6.0 mol of H2 reacts with [tex]N2:6.0 mol H2 × (2 mol NH3/3 mol H2) = 4.0 mol NH3[/tex]

10) A thermometer showed a temperature of 28° C. 9C = 5 (F32) can be used to find the in degrees Fahrenheit, F, given the in degrees Celsius, C. What was the in degrees Fahrenheit? temperature temperature temperature​

Answers

Step-by-step explanation:

Using the formula F = (9/5)*C + 32, where C is the temperature in Celsius and F is the temperature in Fahrenheit, we can find the temperature in Fahrenheit:

F = (9/5)*C + 32

F = (9/5)*28 + 32

F = 82.4

Therefore, the temperature in degrees Fahrenheit is 82.4°F.
