An experimenter was interested in dieting and weight loss among
men and women. It was believed that women tend to lose more weight
than men in the first 2 weeks of a standard dieting program. A
random sample of 15 married coupes were put on the same diet. Their
weight loss after 2 weeks is listed below. Conduct a directional
t-test of the difference using .05 as your level of significance.
Be sure to complete all steps.
