Given that a sample of 32 cowboys gave the following years of longevity:
58 52 68 86 72 66 97 89 84 91 91
92 66 68 87 86 73 61 70 75 72 73
85 84 90 57 77 76 84 93 58 47
The stem and leaf display for the data is given as follows:
4 | 7
5 | 2, 7, 8, 8
6 | 1, 6, 6, 8, 8
7 | 0, 2, 2, 3, 3, 5, 6, 7
8 | 4, 4, 4, 5, 6, 6, 7, 9
9 | 0, 1, 1, 2, 3, 7
55% x n = 33
divide 33 by .55
n = 60
