#10. The following data represent annual salaries, in thousands
of dollars, for employees of a small company.
54 55 55 57 57 59 60 65 65
65 66 68 68 69 69 70 70 70
75 75 75 75 77 82 82 82 88
89 89 91 91 97 98 98 98 280
(a) Make a histogram using the class (cell) boundaries 53.5,
99.5, 145.5, 191.5, 237.5, and 283.5.
(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 280 thousand dollars. Make a
new histogram using the class (cell) boundaries 53.5, 62.5,
71.5, 80.5, 89.5, and 98.5. Does this histogram reflect the
salary distribution of most of the employees better than the
histogram in part (a)?

Use six classes or cells to do the following.
(a) Find the class width or cell interval.
(b) Make a frequency table showing the class limits, class or
cell boundaries, midpoints, frequencies, relative or
normalized frequencies, and cumulative frequencies.
(c) Draw a histogram.
(d) Draw a relative or normalized frequencies histogram.
(e) Categorize or characterize the basic distribution shape as
uniform, moun-shaped, symmetric, bimodal, skewed left or
right.
(f) Draw an Ogive graph.
(g) Interpretation Discuss some of the features about the data
that the graphs reveal. Consider items such as data range,
location of the middle half of the data, unusa values,
outliers, etc.
20. Advertising: Readability The following is a list of the
number of three-syllable (or longer) words in advertising copy
of randomly selected magazine advertisements.
