The data from Exercises 8 and 9 in Chapter 7 are reproduced in the tables that follow.

a. Compute the Pearson r for Data Set 3, Chapter 1, and test for significance at the .01 level.

b. Use the z scores you calculated for these data in the exercises of Chapter 4 to recompute the r with the zproduct formula. Is it the same?

c. Compute the Pearson r for Data Set 3, Chapter 1, with X rearranged, and test for significance at the .05 level.
