A researcher was interested in investigating a relationship between the age (independent variable) of a driver and the distance the driver can see. For this purpose, he collected data on some drives. The data is provided in Appendix ‘1”.

To help you, partial summary analysis is provided below: SSxx= 13,752 SSxy=- 41,350 SSyy=193,667 ∑ x = ∑ Age = 1,530; ∑ y = ∑(Distance the driver can see)=12,700

a) Write the estimated regression line

b) Is the relationship meaningful (significant at α=0.05)? (3 pts) – make sure to state the null and alternative hypothesis first.

c) What is the strength of the relation? It is significant? (3 pts)

d) What is the coefficient of determination? (2 pts)

e) John is 61 years old. What is the expected driving distance for him? What is the 95% prediction interval for John? (4 pts)

1. Consider a US company that imports German goods. What effect will a sudden depreciation of the dollar relative to the euro have on the P/E ratio of the U.S. company? Discuss the effect both the possibilities—the company being able to completely pass through the dollar depreciation to its customers and the company being unable to completely pass through the dollar depreciation to its customers.

Rundell Corporation uses customers served as its measure of activity. The following report compares the planning budget to the actual operating results for the month of July. Wages and Supplies are purely variable costs while Insurance is all fixed cost. Miscellaneous expense is a mixed cost with $2,500 being the fixed component of the total amount planned.

Required: Using the Planning budget column and the assumptions above, determine the unit variable costs and the fixed costs needed to build the Flexible Budget then complete the Revenue and Spending Variances and the Activity Variances for each revenue and expense account and the appropriate totals. You may prepare the Flexible Budget amounts on a separate worksheet and submit, but it is not required.Round answers to whole amounts, use commas if necessary and no dollar signs.

A telephone sales force can model its contact with customers as a Markov chain. The six states of the chain are as follows:
State 1 Sale completed during most recent call
State 2 Sale lost during most recent call
State 3 New customer with no history
State 4 During most recent call, customer’s interest level low State 5 During most recent call, customer’s interest level medium State 6 During most recent call, customer’s interest level high
Based on past phone calls, the following transition matrix has been estimated:

a) For a new customer, determine the average number of calls made before the customer buys the product or the sale is lost.
b) What fraction of new customers will buy the product?
c) What fraction of customers currently having a high degree of interest will buy the
product?
d) Suppose a call costs 20 TL and a sale earns 200 TL in revenue. Determine the “value”
of each type of customer.
