1.5 Twenty adult males between the ages of 30 and
\n40 participated in a study to evaluate the effect of a
\nspecific health regimen involving diet and exercise on
\nthe blood cholesterol. Ten were randomly selected to
\nbe a control group, and ten others were assigned to
\ntake part in the regimen as the treatment group for a
\nperiod of 6 months. The following data show the reduction
\nin cholesterol experienced for the time period
\nfor the 20 subjects:
\nControl group: 7 3 \u22124 14 2
\n5 22 \u22127 9 5
\nTreatment group: \u22126 5 9 4 4
\n12 37 5 3 3
\n(a) Do a dot plot of the data for both groups on the
\nsame graph.
\n(b) Compute the mean, median, and 10% trimmed
\nmean for both groups.
\n(c) Explain why the difference in means suggests one
\nconclusion about the effect of the regimen, while
\nthe difference in medians or trimmed means suggests
\na different conclusion.<\/p>\n
