The body mass index (BMI) of a person is defined to be the person's body mass (in kg) divided by the person's height (in m2 ). Consider a population of males with a mean BMI of 3.2 kg/m2 and standard deviation of 0.17 kg/m2 . We select n = 33 individuals from this population. (a) Let X be the mean BMI for the 33 individuals. Give the expected value and the standard deviation of X. (b) Compute P(X > 3.3)
