a. Calculate the power your test would have in Exercise 7 of Chapter 7 if the two sets of scores were not correlated at all in the population (use g for those data as d in your power calculation).

b. Calculate the power your test would have in Exercise 7 of Chapter 7 if the two sets of scores had a population correlation of ρ = .5 (again, use g for those data as d in your power calculation).
