A person’s muscle mass is expected to be associated with age.Some people also thought exercise time would be associated with themuscle mass. To explore the potential relationships between musclemass and age, muscle mass and exercise time, a nutritionistrandomly selected 20 women from a population of women with ageranging from 40 to 80 years old, and measured their muscle mass (ascore without unit) and exercise time (hours per month)
