For the regression analysis of the data in Exercise 15.79:
a. Use the 0.05 level in testing whether the population coefficient of correlation could be zero.
b. Use the 0.05 level in testing whether the population regression equation could have a slope of zero.
c. Construct the 95% confidence interval for the slope of the population regression equation. Discuss the interval in terms of the results of part (b).
