Question: Medicine and Clinical Studies Many people consume protein shakes to help build muscle mass and eliminate body fat. In a recent study, the amount of protein in two competing drinks was compared. Independent random samples were obtained, and the protein content (in grams) in each drink was measured. The summary statistics and known variances are given in the following table.
Is there any evidence to suggest that the mean amount of protein is different in these two products? Use a = 0.01 and assume normality.
