You need to calculate the F statistic, set up HO and H1, and use the F tables in the textbook to do the test. (10pts)

Explanation / Answer

16.

In the second table, the p-value against 'exper' is given by 'P > | t |' which is 0. Since this value is less than 0.05, So we can argue that 'exper' is significant at 5% level.
