wboys by Connie Brooks (University of New Mexico Press), cowboys were by and large from good families and not necessarily young to die. They were not mostly drunkards, gun gunslingers, or thieves as portrayed in the movies. Does your stem and leaf display of the data support that finding? (answer yes or no). Cowboys: Longevity How long did real cowboys live? One answer may be found in the book The Last Cowboys by Connie Brooks (Univeristy of New Mexico Press). This delightgul book represents a thoughtful sociological study of cowboys in West Texas and Southeastern New Mexico around the year 1890. A sample of 32 cowboys gave the following years of longevity:
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
First find the value of f(2). This is the y coordinate of the point with x = 2 as the x coordinate. Look through the set f and see that (2,-5) is one of the points. This point says x = 2 and y = -5. So f(2) = -5
We will replace the f(2) with -5 to go from this g(f(2)) to this g(-5)
Now repeat the same steps but for g this time Look through the set g for a point with x coordinate of -5. That point is NOT listed. Why not? Because the x values are -3, -1, 0, 1 and 3. None of which are -5. No such point exists.
