A developer wants to know if the houses in two different neighborhoods were built at roughly the same time. She takes a random sample of six houses from each neighborhood and finds their ages from local records. The accompanying table shows the data for each sample​ (in years). Assume that the data come from a distribution that is Normally distributed. Complete parts a through c below.

Neighborhood 1: 62, 46, 61, 57, 49, 43

Neighborhood 2: 52, 34, 46, 43, 42, 53

Some neighborhoods are considered "old" while others are considered "new," with new homes generally selling at a higher price. One way to compare "old" and "new" neighborhoods is to examine...
