10. Critical Thinking The following data represent salaries, in thousands of dol- lars, for employees of a small company. Notice that the data have been sorted in
increasing order.
24 25 25 27 27 29 30 35 35 35 36 38 38
39 39 40 40 40 45 45 45 45 47 52 52 52
58 59 59 61 61. 67 68 68 68 250
(a) Make a histogram using the class boundaries 23.5, 69.5, 115.5, 161.5,
207.5, 253.5.
(b) Look at the last data value. Does it appear to be an outlier? Could this be the
owner's salary?
(c) Eliminate the high salary of 250 thousand dollars. Make a new histogram
using the class boundaries 23.5, 32.5, 41.5, 50.5, 59.5, 68.5. Does this his.
togram reflect the salary distribution of most of the employees better than
the histogram in part (a)?
