The ages of a group of 123 randomly selected adult females have a standard deviation of 17.2 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 17.2 years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students?
