Suppose that you have been invited to a high school reunion. Embarrassingly, you are having a lot of trouble remembering names of your classmates and teachers. Are you the only person who feels the onset of premature senility or is this a typical phenomenon? To find out, you survey a group of adults attending a high school basketball game, asking them to list all the names of their high school classmates and teachers that they can remember. You collect and assign the following scores according to the number of names remembered by each of the subjects in your sample:
63, 49, 98, 22, 56, 87, 98, 34, 23, 65, 87, 65, 44, 46, 47, 83, 76, 67, 34, 56, 53, 65, 47, 85, 32, 98, 54, 37, 48, 64, 49, 74, 69, 75, 57, 84, 38, 37, 85, 45, 65, 54.
