1. The sample you were given in class comes from Data Set 14 “Oscar Winner Age” in your textbook. They are the ages of winners of the Best Actress and Best Actor for the Oscars. Below, please record the sample statistics below and then use them to answer the questions that follow. If you did not receive a sample, please email your instructor for a data set.

                Sample number                                

2. Using the data above based on your samples of Best Actress and Best Actor winners, compute a 95% confidence interval for mean age μ of the Best Actor winners and determine the margin of error.

3. Using the data calculated on page 1 based on your sample of Best Actress winners, test the claim at α = 0.05 significance level that the mean age of Best Actress winners is greater than 40.

                                H₀:                                                         

                                H₁:                                                         

2. Determine the test statistic and the P‐Value

                                Test Statistic:                                                                    

                                P‐Value:                                                                              

3. Make a decision about the null hypothesis. Briefly justify your answer.
4. Write a conclusion that incorporates the original claim directly.

If we recreated the scene from Fast & Furious 7 and dropped a Challenger SRT® Hellcat Redeye Widebody from a C-130 aircraft at 5,280 ft, how much horsepower would it take to drive past it before it hits the ground if you’re 1 mile away?

(Using R Scholar) For each of the distributions, begin by creating 1000 random samples, each of size ?. Then, for each of the 1000 samples, you will calculate the sample average, ?̅. After calculating 1000 different ?̅’s, you will be able to make a histogram and normal probability plot of the ?̅ values and thus visualize the distribution of ?̅. The goal is to see what value of ? is large enough for the distribution of ?̅ to become approximately normal. Notice that this value of ? depends on the population distribution. To determine the value of ? required, your simulations will start from a small ? and progress to larger ?'s. You will assess the normality based on the plots for each ? and continue until either you have finished the values of ? listed or increased the values until observing sufficient normality in the plots.

For each of the distributions below, you will complete the following: (0.2 points) Code: You only need to provide one code listing for each distribution (i.e. you don’t need to repeat the code for each choice of ?).

2. (0.5 points) Histogram/normal probability plots For each of the values of ?, submit a histogram (with the two colored curves) and a normal probability plot. For each of the graph pairs, indicate whether they appear sufficiently normal or not. No explanation is required. Make sure you increase ? until the distribution of ?̅ appears sufficiently normal.

3. (0.3 points) Summary table This table contains the experimental mean and standard deviation calculated from the data (output is required for each value of ?) and the theoretical mean and standard deviation calculated from Equations 1 (with work for one of the values for each distribution where ? ≠ 1). The format for this table for Part B is below. Make sure you increase ? until the distribution of ?̅ appears sufficiently normal.

A. (1 points) Standard Normal Distribution. ? = 1, 3, 7 and 15.

B. (1 points) Uniform distribution over the interval (0, 8). ? = 1, 3, 7 and 15.

C. (1 points) Gamma distribution with parameters ? = ?. ?? and ? = ?. ? = 1, 5, 10, 20, 40, and continue in intervals of 20 if needed until the shape becomes normal. This distribution has population mean and standard deviation of ? = 1.805, ? = 0.95.

D. (1 points) Poisson distribution with parameter ? = ?. ?. ? = 1, 5, 10, 20, 40, and continue in intervals of 20 if needed until the shape becomes normal.

1. Financial institutions in the U.S. economy

Suppose Paolo would like to invest $2,000 of his savings.

One way of investing is to purchase stock or bonds from a private company.

Suppose TouchTech, a hand-held computing firm, is selling stocks to raise money for a new lab—a practice known as _____ (equity or debt) finance. Buying a share of TouchTech stock would give Paolo _________ (a claim to partial ownership in/ an IOU, or promise to pay, from) the firm. In the event that TouchTech runs into financial difficulty, _______ (The bondholders/ Paolo and other stockholders) will be paid first.

Suppose Paolo decides to buy 100 shares of TouchTech stock.

Which of the following statements are correct? Check all that apply.

The price of his shares will rise if TouchTech issues additional shares of stock.

The Dow Jones Industrial Average is an example of a stock exchange where he can purchase TouchTech stock.

Expectations of a recession that will reduce economy-wide corporate profits will likely cause the value of Paolo's shares to decline.

Alternatively, Paolo could invest by purchasing bonds issued by the U.S. government.

Assuming that everything else is equal, a corporate bond issued by an electronics manufacturer most likely pays a ____ (lower/higher) interest rate than a municipal bond issued by a state.

Eric and Pat are baseball fans. They drove to the local stadium in Eric's car to watch a game, and decided to park in the parking garage. When driving into the parking garage, they were required to take a ticket in order to get access to the garage. The cost for parking the car was $15.00, which was not due until exiting the garage. After taking the ticket, they parked the car and then walked across the street to the game. When the game was over, they walked back to the car. Upon approaching Eric's vehicle, they noticed that one of the windows had been smashed in. Everything inside had been taken, including Pat's work laptop which had been sitting in a bag in the backseat of the car. Eric and Pat were upset that the parking garage security didn't notice and prevent this crime from happening. Eric and Pat filed a lawsuit against the company that runs the parking garage. The company (ABC Co.) defended, stating that on the back of the ticket is a clause which states the following in conspicuous lettering: "ABC Co. is not liable for any loss of contents or damage caused to vehicles parked in the garage due to its own negligence or the actions of any other person." Will the court uphold the clause on the parking ticket? Make sure to fully explain your answer. This means including the law that applies and the reasoning in applying that law.

Part I. Genetics and Epigenetics

Based on your readings, please explain how you think genetics and epigenetics affects:

us, as persons,

how we view and interact with others,

the kinds of perceptions and judgments we have about people, cultures, and populations,

how public policy, government benefits, corporate structure, and other systemic structures can be changed (if needed), and

how our own values can change or be modified to make room for a new understanding of epigenetics

Part II. Indigenous understanding of Genetics and Epigenetics

Studies in cultural psychology speak of "folk knowledge". Much of these are oral traditions passed down through multiple generations and carry the beliefs, stories, and wisdom of previous generations. One inherent understanding is that heritability that runs in families is not exclusive to the way we look but is extended to the way we act, think, and to how personalities develop. The environment in which we develop is also important to many cultures and traditions. The language used in indigenous psychology does not utilize scientific terms; they used their own terms to explain multi-generational and multi-dimensional inheritance (genetics and epigenetics).

Please describe how your culture explains heritability (genetics and epigenetics). You can incorporate customary practices, beliefs, rituals, myth, and academic studies.

BASIC NET PRESENT VALUE ANALYSIS

Cornell Green, process engineer, knows that the acceptance of a new process design will depend on its economic feasibility. The new process is designed to improve environmental performance. On the negative side, the process design requires new equipment and an infusion of working capital. The equipment will cost $300,000, and its cash operating expenses will total $60,000 per year. The equipment will last for seven years but will need a major overhaul costing $30,000 at the end of the fifth year. At the end of seven years, the equipment will be sold for $24,000. An increase in working capital totalling $30,000 will also be needed at the beginning. This will be recovered at the end of the seven years.

On the positive side, Cornell estimates that the new process will save $135,000 per year in environmental costs (fines and cleanup costs avoided). The cost of capital is 10 percent.

Required:

1. Prepare a schedule of cash flows for the proposed project. Assume that there are no income taxes.

2. Compute the NPV of the project. Should the new process design be accepted?

Describe a situation where you would use a Chi-squared test by stating

1. your sample and two variables or two samples and one variable,

2. whether or not the test would be one of homogeneity or independence,

3. Both a null and an alternative hypotheses, and

4. a significance level. Then find

5. the degrees of freedom of your chi-squared statistic,

6. the rejection region for your test and state

7. what a chi-squared statistic value in this region would imply for your test. Remember that you do not need to list the values of the variable for individuals in either the samples or the population, and that the value for 4 does not need to be calculated, only stated.

Please review the following scenario and place yourself in the position of the new Human Resource Manager for Acme Manufacturing. Once you understand the circumstances of the problems in this organization, please respond to the questions that the General Manager has posed.

Scenario: You just started work as the new Human Resources Manager for Acme Manufacturing, a Fortune 1,000 company. The job was vacant for 6 months prior to your hiring. You have wondered about this, especially since reading about employee harassment incidents and fights recently in the news.

The General Manager (GM) calls you into his office the minute you arrive. He shuts the door after saying a quick word of welcome and begins to tell you about an incident that happened last week that needs your immediate attention. The company's manufacturing operation runs three shifts of production workers so that the plant is operating 24/7. Over the past 6 months, hostilities have arisen between employees on the third and first shifts. What started out as jeering and criticisms by the first shift, claiming they have to clean up the mess and complete all of the work left undone by the third shift, has escalated to physical confrontations and altercations. Although the GM says that aggressive bantering back and forth is common for shift workers in manufacturing, he admits that he is worried about further violent escalation. The GM says he needs your help.

• Where do you think that this evaluation should begin? In your reply, explain your reasoning.
• Explain the different levels of disciplinary actions that will be used for the Acme Manufacturing Company. Your reply should include the levels of discipline and 1 example of a disciplinary action for each level.
• How would you determine the disciplinary action appropriate for the employees involved in this scenario? Your response should include your reasoning.
• Why would you draft policies and procedures associated with disciplinary actions for the workplace? Provide a minimum of 2 reasons in your response.
• How would you ensure that the entire workforce is trained on these new policies and procedures? Provide 1 example in your response.

Write a 5–7-page memo to the GM that provides your responses to his questions above. Be sure to cite any references used in proper APA format.
