Chapter 14, Problem 36PS

In Problem 14.6 on page 542, you used full-time voluntary turnover $\left(\%\right)$ , and total worldwide revenue $\left(\text{\$billions}\right)$ to predict the number of full-time job opening (stored in BestCompanies). Using the result from that problem,

a. at the 0.05 level of significance, determine whether each independent variable makes a significant contribution to the regression model. On the basis of these results,

b. compute the coefficients of partial determination, $r^2{}_{Y1.2}\text{and}{r}^2{}_{Y2.1},$ and interpret their meaning.
