a. Use the F test at level .05 to test H0: 1 2 3

4 5 versus Ha: at least two is are unequal.

b. What can be said about the P-value for the test?

2. Suppose that the compression strength observations on the fourth type of box in Example 10.1 had been 655.1, 748.7, 662.4, 679.0, 706.9, and 640.0 (obtained by adding 120 to each previous x4j

). Assuming no change in the remaining observations, carry out an F test with .05.
