It is desired to compare the average ages at which men and women get their first license to drive. A random sample of 75 men yielded a mean and standard deviation of 17.3 and 4.7 years, respectively. A random sample of 96 women yielded a mean and standard deviation of 19.6 and 5.1 years, respectively. If it is desired to estimate the mean difference to within 1.5 years with 95% confidence, how large a sample should be taken from each population? Assume n1 = n2 = n.
