A statistics class collected data about male and female heights. The sample of 143 females had a mean height of 64 inches with a standard deviation of 2.84 inches. Assuming that the standard deviation of all such female heights is 2.60 inches, use a 0.05 significance level to test the claim that women’s heights have a mean different from 63.8 inches. We are testing the claim about a (mean, proportion, standard deviation): ______________________ Which test will you use (proportion, z-test,...
