(1) Answer both questions below about the EOQ model.

(a) In the EOQ model, unit product cost or selling price, C, is not included in the formula we use to solve for the economic order quantity. Explain why it is not necessary to include this information in the EOQ formula.

(b) What are the major limitations of the EOQ model?

It is suggested that the average IQ of top civil servants, research scientists and professors is 140. Suppose that the standard deviation is 5.
a. Suppose a full professor from a Canadian university is selected at random. What is the probability that the IQ of the selected Canadian professor is below 130? State any necessary assumptions you have made to compute this probability.

b. Suppose that the assumption(s) made in part a was not justifiable. A researcher decided to take a random sample of 81 full professors from the Canadian University system.

i. What is the sampling distribution of the sample mean ¯ x ? Explain.

ii. Find the mean and standard deviation of the sampling distribution of ¯ x.

iii. What is the probability that the sample average of this sample is less than 130? Compare your answer with the answer given in a. Summarize your findings.

iv. Will the probability in (iii) change if you change the wording from “less than” to “less than or equal to”? Why or why not?

v. Can you compute the probability that the sample average IQ is exactly 135? Justify your answer.

vi. If the sample mean ¯ x is actually actually 130, what can be said about the claim that µ = 140.

vii. What is the probability that the sample mean differs from the population mean by more than 2?

viii. Within what limits do you expect the sample average to be with the probability 0.95?

Pretend you are a prospector and a blacksmith who wants to make a belt buckle made of iron. (Your pants keep slipping downward and you have a leather belt, but no buckle.) What mineral are you looking for, and where? What are you going to do to turn your mineral into a belt buckle. (You are going to make it by yourself.) Describe every step along the way, in detail.

The CEO of the company claims that the mean work day of the company’s mechanical engineers is less than 8.5 hours. A random sample of 25 of the company’s mechanical engineers has a mean work of 8.2 hours. Assume the population standard deviation is 0.5 hour and the population is normally distributed. At ​​α​​​​ = 0.01, test the CEO’s claim.

• State Ho and Ha and identify the claim.
• State the tail of the hypothesis test.
• State the level of significance.
• State the critical value and explain why you chose a z or a t-test.
• Complete the hypothesis test.
• State your conclusion.
• Discuss the possibility of a Type I or Type II error.
