Unformatted text preview: problem (propose a dierent design, identify the design and explain how you would test for a route eect)? 3. Gulf, Florida and South Carolina red snapper are tested for population homogeneity. Suppose the variation in the number of times a short tandem repeat marker appears at a polymorpic site has standard deviation 10. How many sh from each population should be sampled if treatment eect = (4 , , 4) is to be detected with 80% power ( = . 05)? Suppose we want to study treatment eect = (k, , k ) as a function of sample size. What sample sizes do we need to detect with 80% power for choices of k from 4 to 10? 1...
