In the following study the city of Saskatoon was interested in knowing the number ofhours per month that families in two areas of the city made use of a recreational facility. Itwas also interested to know if there was a difference between the two areas. A sample ofsize n = 45 families were selected from Area 1 resulting in a mean (hours used per familyper month) of 15.6 and a standard deviation of 4.5.A second sample of size m = 50 families were selected from Area 2 resulting in a mean(hours used per family per month) of 20.7 and a standard deviation of 3.7.

Suppose that one is interested in determining if there is a difference in the mean number of hours per month that the recreational facility is used between families in Area 1 and families in Area 2

question parts are given in pics and I have asked only three subparts.
