Assume that the sample sizes for the two groups from Problem 1 are: Nopposite-sex =

200; Nsame-sex = 100.

a. Recalculate the standard error and sample z-score with these new sample sizes.

b. Should the null hypothesis be rejected given these new sample sizes? (Use the same alpha-level, .025, as in Problem 1.)

c. Explain why we would draw different conclusions depending on the sample sizes from Problems 1 and 2.
