6. Find the 85% condence interval for 13(le = 40). In book notation this is the con dence interval for E(Yh) with .17; = 40. The point estimate E(Y|$ = 40) is n and the variance for this estimate is _ 2 32(3)\" = MSE l + Sshm) \" 2m a:~)2 i=1 Some R code to help you get started with these types of questions. The following assumes you have already created the variables MSE and u (see homework 1)
