. A person's protein requirement is the amount of protein they must consume in a day to maintain a stable weight, muscle mass, etc. A group of researchers wanted to know if the mean protein requirement (in grams of protein per day per kilogram of body weight) is the same for young adult males and females. The protein requirement of 10 males and 11 females was determined. The protein requirements of the subjects are given below. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. (Data based on summary statistics in CampbelWW, et al., Dietary protein requirements of younger and older adults American Journal of Clinical Nutrition. 2008) Males: 0.74, 0.76, 0.59, 0.44, 0.46, 0.51, 0.63, 0.29,0.43,0.59 Females: 0.82, 0.80, 0.68, 0.51, 0.54, 0.63, 0.70, 0.80, 0.49, 0.74, 0.62 a. is there a difference in the mean protein requirement of young adult males and females?
