[See Solution] You want to test whether serum cholesterol levels differ in vegetarian and non-vegetarian. Your goal is to test for a difference at =.05
Question: You want to test whether serum cholesterol levels differ in vegetarian and non-vegetarian. Your goal is to test for a difference at =.05 (two-sided) with power 0.80. Assume populations are normal with standard deviation 40 mg/dl. Based on these assumptions how many people do you need to study to detect a mean difference of 10 mg/dl.
