The ages of a group of 137 randomly selected adult fermales have a standard deviation of 16.5 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let a = 16.5 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? Assume that we want 90% confidence that the sample mean is within one-half year ot the population mean. The required sample size is (Type a whole number.)
