Question: Below is a table showing some of the results from
Below is a table showing some of the results from the multiple regression analysis described in Exercise 15. Here we were attempting to link winning percentage (y) to daily practice time (x1), average speed of first serve (x2), and first serve percentage (x3) based on data from a group of 12 professional tennis players who were monitored over the past year.
Based on the F test described earlier, we were able to reject the “All f s are 0” null hypothesis. Now use the t test to determine which, if any, of the individual coefficients are statistically significant at the 5% significance level.
