The owner of a local clothes shop wants to know if there is a difference between the average ages of males and females customers. He randomly samples 42 men and 44 women customers this month. He finds the average age of the men to be 29.07 with a standard deviation of 5.343. The average age of the women was 32.68 with a standard deviation of 9.656. Is there evidence of a difference between the mean ages for 2 genders?
