Textbook Question
Chapter 15, Problem 53SE
Recall that in exercise 50 the personnel director for Electronics Associates developed the following estimated regression equation relating an employee’s score on a job satisfaction test to length of service and wage rate.
ŷ = 14.41 − 8.69x1 1 13.52x2
where
x1 = length of service (years)
x2 = wage rate (dollars)
y = job satisfaction test score (higher scores indicate greater job satisfaction)
A portion of the Minitab computer output follows.

Regression Equation
y = 14.41 − 8.69 X1 + 13.52 X2
- a. Complete the missing entries in this output.
- b. Compute F and test using α = .05 to see whether a significant relationship is present.
- c. Did the estimated regression equation provide a good fit to the data? Explain.
- d. Use the t test and α = .05 to test H0: α1 = 0 and H0: β2 = 0.

Your personal trainer suggests that you supplement with at least 10 grams of creatine, 39 grams of L-glutamine, and 90 grams of BCAAs each week. You are thinking of combining Xtend and Gainz to provide you with the required nutrients. How many servings of each should you combine to obtain a week's supply that meets your trainer's specifications at the least cost? (If an answer does not exist, enter DNE.)
