A marketing study was conducted to compare the variation in the age of male and female purchasers of a certain product. Random and independent samples were selected for both male and female purchasers of the product. The sample data is shown here:

Female: n = 31, sample mean = 50.30, sample standard deviation = 13.215
Male: n = 21, sample mean = 39.80, sample standard deviation = 10.040
