The ages of a group of 148 randomly selected adult females have a standard deviation of 17.5 years. Assume that the ages of female statistics students have less variation than ages of females in the general population so let o= 17.5 years for the sample Size calculation. How many female statistics students ages must be obtained in order to estimate the mean age of all female statistics students? Assume that we want 99% confidence that the sample mean is within 1/2 year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation and ages of females in the general population?
