5.) Name all of the functions of inventory from your textbook. How are these functions affected by lead time, specifically whether lead times are very long, or relatively short? How does an increase, or decrease in lead time affect inventory carrying cost?
6.) Identify a project that you are interested in other than the fundraiser or job search we worked on in class. Identify the major steps of this project, and which of these are on the critical path. Then show the last step of the project and estimate the total time for the project. Use figure 17.3 from your textbook and Table 17.2 to help develop your answer. NOTE: Estimating the total project time will require developing a general understanding of what needs to be done between the first steps and the last step.
7.) If you were an operations manager for an organization (service or manufacturing) with at least 1,000 employees what three strategies would you use to make the operation as successful as possible? What is your rationale for each of the three strategies? What is one thing that might go wrong with each of these three strategies? Approach this question by first identifying a specific business, or type of business. (Note that if you are managing 1000 employees there will be a number of levels between you and the lower level employees. This is an operations question – so the response is related to operational challenges – not sales, marketing, finance, or accounting). Do not use Apple, Cargill, or Walmart.
8.) You are the owner of a small manufacturing company with 300 employees. What would be your top 5 operational strategies for making your company successful. (Do not use marketing, sales, accounting, or finance strategies). Give two specific reasons for choosing each of these five strategies (10 total reasons/justifications). Finally, give three reasons why you believe – not feel – these strategies would lead to success.

The Josephus problem is named after the historian Flavius Josephus, who lived between the years 37 and 100 CE. Josephus was a reluctant leader of the Jewish revolt against the Roman Empire. When it appeared that Josephus and his band were to be captured, they resolved to kill themselves. Josephus persuaded the group by saying, “Let us commit our mutual deaths to determination by lot. He to whom the first lot falls, let him be killed by him that hath the second lot, and thus fortune shall make its progress through us all; nor shall any of us erish by his own right hand, for it would be unfair if, when the rest are gone, somebody should repent and save himself” (Flavius Josephus, The Wars of the Jews, Book III, Chapter 8, Verse 7, tr. William Whiston, 1737). Yet that is exactly what happened; Josephus was left for last, and he and the person he was to kill surrendered to the Romans. Although Josephus does not describe how the lots were assigned, the following approach is generally believed to be the way it was done. People form a circle and count around the circle some predetermined number. When this number is reached, that person receives a lot and leaves the circle. The count starts over with the next person. Using the circular linked list developed in Exercise 6, simulate this problem.
Your program should take two parameters: n, the number of people that start, and
m, the number of counts. For example, try n = 20 and m = 12. Where does Josephus need to be in the original list so that he is the last one chosen?

Question
Dr. Gamble had been teaching PSYC 2021 for years, and always wore a
suit to class. His average teaching evaluation across all courses
and years was 4.2/5. As Dr. Gamble was preparing for an upcoming
PSYC 2021 course (N = 132), he wondered whether his course
evaluations would be lower than the average across all of his
previous classes if he wore jeans and a t-shirt to every class in
the upcoming term. Use null hypothesis testing (all steps) to
determine if wearing jeans and a t-shirt will lower Dr. Gamble’s
teaching evaluations, relative to the mean of all previous sections
of the course. Note that only 59 of the 132 students completed a
teaching evaluation. Be sure to appropriately interpret the
confidence interval and effect size (even if it is subjective) and
include a general summary of the results. Use α = .10. Show excel
formula used.

Break-Even EBIT and Leverage Coldstream Corp. is comparing two different capital structures. Plan I would result in 3,700 shares of stock and $13,700 in debt. Plan II would result in 3,100 shares of stock and $30,140 in debt. The interest rate on the debt is 7 percent.
a. Ignoring taxes, compare both of these plans to an all-equity plan assuming that EBIT will be $7,600. The all-equity plan would result in 4,200 shares of stock outstanding. Which of the three plans hast the highest EPS? The lowest?
b. In part (a), what are the break-even levels of EBIT for each
plan as compared to that for an all-equity plan? Is one higher than
the other? Why?
c. Ignoring taxes, when will EPS be identical for Plans I and II?
d. Repeat parts (a), (b), and (c) assuming that the corporate
tax rate is 40 percent. Are the break-even
levels of EBIT different from before? Why or why not?

chi-squared test ( χ2 test) problem
We're interested in the weight of babies born not prematurely but
after a pregnancy shorter than average. Of a sample of 300 children
born in April, the found as follows:
. born after 37 weeks: 30 slightly underweight; 20 normal weight.
. born after 38 weeks: 40 slightly underweight; 60 normal weight.
. born after 39 weeks: 50 born slightly underweight; 100 normal weight.
(a) Identify the two variables studied in the sample and the values of the two variables they can take, then build a full frequency table.
b) Calculate the value χ2 from the table obtained in a). Explain why we can be almost certain that there is an interdependence between the number of weeks of pregnancy and birth weight.
(c) As it has been found that there is an interdependence between the two, an attempt will be made to establish a numerical relationship between the number of weeks of pregnancy and the proportion of children born underweight. What will our variables be here and what does our study tell us?
d) Calculate the equation for the regression line obtained from the
points found in c).
