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. a) Determine 95% confidence limits for the mean of Area 2. a) 20.358 to 21.042 b) 20.282 to 21.118 c) 20.206 to 21.194 d) 20.130 to 21.270 e) 20.054 to 21.346 f) 19.978 to 21.422 g) 19.902to 21.498 h) 19.826 to 21.574 i) 19.750 to 21.650 j) 19.674 to 21.726 b) Determine 95% confidence limits for the difference in means between Area 2 and Area 1. a) 3.735 to 6.465 b)3.333 to 6.667 c) 3.129 to 7.071 d) 2.826 to 7.374 e) 2.522 to 7.678 f) 2.219 to 7.981 g) 1.916 to 8.284 h) 1.613 to 8.587 i) 1.309 to 8.890 j) 1.006 to 9.194 c) Determine 99% confidence limits for the difference in means between Area 2and Area 1. a) 3.583 to 6.617 b) 3.245 to 6.955 d) 2.571 to7.629 e) 2.234 to 7.966 f) 1.897 to 8.303 g) 1.559 to 8.641 c)2.808 to 7.192 h)1.222 to 8.978 i) 0.885 to 9.315 j) 0.548 to 9.652
