Question

Data were collected on annual personal time (in hours) taken by a random sample of 16 women (group 1) and 7 men (group 2) employed by a medium sized company. The women took an average of 26.874 hours of personal time per year with a standard deviation of 2.84 hours. The men took an average of 24.89 hours of personal time per year with a standard deviation of 3.29 hours.
