Questions 13-15 are based on the following American workers spend an average of 60 minutes to and from work in a typical day. You obtain the following random sample of employed adults in Indianapolis metropolitan area (IMA) to test the hypothesis below: 49 48 59 52 79 38 58 79 61 50 87 53 45 83 49 47 34 70 68 94 66 81 73 64 68 77 56 72 52 45 47 63 43 84 67 43 74 52 55 54 56 55 77 49 53 64 68 57 61 50 69 79 33 65 75 51 49 56 48 56 60 67 34 77 67 86 41 87 58 75 79 56 60 56 74 71 61 60 34 65 46 63 66 56 47 81 39 75 80 52 69 42 77 77 63 43 60 66 68 46 73 43 65 59 82 61 81 97 Is there enough evidence, at a = 0.05, to conclude that the average commuting time in IMA is greater than the national average?
