Among the 52 inhabitants of TOWN 2, the mean number of hours of volunteer work per year was 38, with standard deviation 8. Test the claim that the mean number of hours volunteered by all residents of TOWN 1 is more than ten hours greater than the mean number of hours volunteered by all residents of TOWN 2
