Chapter 3, Problem 98CRE

Students’ Ages Here are the ages of some students in a statistics class: 17, 19, 35, 18, 18, 20, 27, 25, 41, 21, 19, 19, 45, and 19. The teacher’s age is 66 and should be included as one of the ages when you do the calculations. The figure shows a histogram of the data.

a. Describe the distribution of ages by giving the shape, the numerical value for an appropriate measure of the center, and the numerical value for an appropriate measure of spread, as well as mentioning any outliers.

b. Make a rough sketch (or copy) of the histogram, and mark the approximate locations of the mean and of the median. Why are they not at the same location?
