The following frequency distribution table gives the age distribution of drivers who were at fault in auto accidents that occurred during a 1-week period in a city.
Age (years) f
18 to less than 20....... 7
20 to less than 25....... 12
25 to less than 30....... 18
30 to less than 40....... 14
40 to less than 50....... 15
50 to less than 60....... 16
60 and over.......... 35
a. Draw a relative frequency histogram for this table.
b. In what way(s) is this histogram misleading?
c. How can you change the frequency distribution so that the resulting histogram gives a clearer picture?
