For the one-way analysis of variance model, we write the jth observation from the ith group as
Xij = µ + Gi + eij
where m is the overall mean, Gi is the effect specific to the ith group, and eij is a random error for the jth observation from the ith group. Consider the data of Example 15.1.
a. Estimate µ.
b. Estimate Gi for each of the three magazines.
c. Estimate e32, the error term corresponding to the second observation (8.28) for the New Yorker.
