The common expectation is that muscle mass decreases with age. To further examine the relationship between muscle mass and age in women, a nutritionist randomly selected 60 female patients from her clinic: 15 women from each 10-year age group beginning with age 40 and ending with age 80. Each patient's age and current muscle mass was recorded. A scatterplot is shown below. The p-value for these data was less than 0.0001. Write a conclusion of the test in the context of the study. Strong evidence does not exist that an increase in age causes a decrease in muscle mass. Strong evidence exists that an increase in age causes a decrease in muscle mass. Strong evidence exists that age is negatively correlated with muscle mass. Strong evidence does not exist that age is negatively correlated with muscle mass
