The acceptance region for the F-statistic in Example 5.1 can be written as 206; 2,7) and note that the estimator

a. Plot this region as a function of 3, and (1.118,-282) lies outside of the region and leads to the rejection of the hypothesis, HB, By=a

b. Plot the 95% acceptance intervals based on the t-statistic for the individual hypotheses, HB-0 on the plot from part a and explain the apparent contradiction noted in the discussion of Example 5.1.

c. Comment on the effect of correlation in this analysis.
