Question 5.40

10. Focus on the variable "Career Years" in Table 5.13. (Note that the career years were based on data from 2014. Some players continued after 2014, which is noted by 2014+ in the "Last Career Year" column.)

(a) Make two histograms for career years. Use the following class intervals for your two histograms.

  • Histogram 1: 5210, 10215, 15220, 20225, and 25230.
  • Histogram 2: 527, 729, 9211, 11213, 13215, 15217, 17219, 19221, 21223, 23225, 25227, and 27229.

If a data value falls on the boundary of a class interval, classify that data value in the interval to the right. (For example, a player with 10 career years would be counted in the interval 10-15 for histogram 1.)

(b) Describe the overall shape of each of the two histograms. Did changing the class intervals affect the shape of the distribution? Explain.
