For the data in Table 10.1, the ANOVA F test and Welch’s test were not significant with α = .05. Imagine that you want power to be 0.9 if the mean of one of the groups differs from the others by 0.2. (In the notation of Section 10.3, a = .2.) Verify that according to the R function bdanova1, the required sample sizes for each group are 110, 22, 40, and 38.
