Continuing with the walleye.rda (Exercise 13.1), assume that

the samples’ variances approximately equal the population variances. Set α

= 0.05, power between 0.6 and 0.9 and detectable difference between −1

and 1 kg. With these:

1. Draw and interpret a figure for these data similar Figure

13.2.

2. What would be the sample size necessary to detect a

difference of 0.2 kg with power = 0.9?
