1. In Example 9.7.1, the simultaneous confidence intervals (9.133)

reduce to (9.137).

2. What change is needed in the confidence intervals of Example 9.7.1 if the v’s are not required to satisfy (9.136), i.e., if simultaneous confidence intervals are desired for all linear functions vi ξi instead of all contrasts? Make a table showing the effect of this change for s = 2, 3, 4, 5; ni = n = 3, 5, 10.
