a. what test should you use to test the two data sets (male and female life expectancy) for normality and why? (2 points)

b. Run that test on both variables.   Report the results below (2 points).  

3. What do you conclude in each case. Explain! (2 points)

4. Should you use a Pearson’s or a Spearman’s Rank Correlation for this data? Why? (2 points)

e. Calculate the correlation coefficient using SPSS. What is the value of r for this data set? (2 points)

6. What do you conclude about the type of correlation (positive / negative, significant / non-significant)? Explain using information from the SPSS output (3 points)

For questions 2-7: state the appropriate hypotheses; conduct a hypothesis test using α = 0.05 utilizing the classical approach, confidence interval approach, or p-value approach; state the decision regarding the hypotheses; and make a conclusion.

3. (15 pts) In a study of schizophrenia, researchers measured the activity of the enzyme monoamine oxidase (MAO) in the blood platelets of 18 patients. The results (expressed as nmol benzylaldehyde product per 108 platelets) were as follows:

6.8 8.4 8.7 11.9 14.2 18.8

9.9 4.1 9.7 12.7 5.2 7.8 7.8

7.4 7.3 10.6 14.5 10.7

The researchers believe that the average MAO level should be 7.5 amongst the general population, which is assumed to follow a normal distribution. Elevated MAO levels are considered abnormal.

7. (15 pts) The manager of a fast-food restaurant claims that the average service time is less than 90 seconds. A random sample of customers is selected and their wait times are reported as follows:

Halifax Manufacturing allows its customers to return merchandise for any reason up to 90 days after delivery and receive a credit to their accounts. All of Halifax's sales are for credit (no cash is collected at the time of sale). The company began 2021 with a refund liability of $390,000. During 2021, Halifax sold merchandise on account for $12,800,000. Halifax's merchandise costs it 70% of merchandise selling price. Also during the year, customers returned $370,000 in sales for credit, with $204,000 of those being returns of merchandise sold prior to 2021, and the rest being merchandise sold during 2021. Sales returns, estimated to be 3% of sales, are recorded as an adjusting entry at the end of the year.

What is the amount of the year-end refund liability after the adjusting entry is recorded?

1. Research has shown that for a company’s toy truck every increase of $0.10 in the price will

result in 200 fewer sales. At one point, when the price was $2.35, the company sold 18,500

trucks. A reasonable employee of the company wondered aloud what price would maximize

the revenue generated by the sale of the trucks for the company.

a.) Determine the formula of the function N(x) that gives the number of trucks sold when

the price is x dollars. Draw a graph of the function N(x).

b.) Determine the formula for the function R(x) that gives the revenue generated when

the price is x dollars. Graph y=R(x).

c.) Determine algebraically the price that yields the maximum revenue. How much

revenue is generated? How many trucks are sold at this price?

d.) Let’s say that the company wants to sell 20,000 trucks. How much should they

charge and how much revenue is generated?

e.) What is the average rate of change in revenue from x=$2.50 to x=$2.85? What is the

average rate of change from x=$3.00 to $3.25? What units are associated with the

average rate of change? Interpret each average rate of change in the context of the

given situation. What do these average rates of change tell you about the shape of the

graph of R(x)?
