Homework # 6 1. Continuation of # 1 from HW5 (By hand) #6.27 from textbook: In a small scale regression study, the following data were obtained: Y X1 X2 42 7 33 33 4 41 75 16 7 28 3 49 91 21 5 55 8 31 For X1 = 10, X2 = 30, compute 95% confidence interval for the mean response and the prediction interval. Additionally, compute simultaneous 95% confidence sets for regression coefficients using Bonferroni and exact (ellipsoid) method. Can we conclude that the regression coefficients are significant using these confidence sets
