Textbook Question
Chapter 4.4, Problem 44E
The U.S. Census Bureau (2000 census) reported the following relative frequency distribution for travel time to work for a large sample of adults who did not work at home:
- a. Draw the histogram for the travel time distribution. In constructing the histogram, assume that the last interval in the relative frequency distribution (90 or more) ends at 200; so the last interval is 90 to <200. Be sure to use the density scale to determine the heights of the bars in the histogram because not all the intervals have the same width. (Hint: Histograms were covered in Chapter 3.)
- b. Describe the interesting features of the histogram from Part (a), including center, shape, and variability.
- c. Based on the histogram from Part (a), would it be appropriate to use the
Empirical Rule to make statements about the travel time distribution? Explain why or why not.
