y = job satisfaction test score (higher scores indicate greater job satisfaction)
A portion of the Minitab computer output follows.
a. Complete the missing entries in this output.
b. Compute F and test using a = .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 a = .05 to test H0: β1 = 0 and H0: β2 = 0.
