Question: a. Calculate g from the pooled-variance t value you computed to solve Exercise 2 in Chapter 7. Use that value for g as your estimate

a. Calculate g from the pooled-variance t value you computed to solve Exercise 2 in Chapter 7. Use that value for g as your estimate of d, and compute the sample sizes you would need for power = .9, for a .05 two tailed test, assuming that you plan to use two equal-size samples to compare Turck and Dupre Halls.

b. Given the sizes of the samples in Exercise 2 of Chapter 7, how large would d have to be to obtain power = .8, for a .05, two-tailed test?
