4.12 Test scores from an exam had an average of 100, and a standard deviation of 10 (1-pt) Given: H = 100 0= 10 How many Standard Deviations is 80 below the Mean? How many Standard Deviations is 120 above the Mean? What % of test Scores fall between 80 and 120? Hint: apply the 68% - 95% - 99.7% Rule 4.18 Skinfold thickness over the skin of the triceps muscle in the arm (5 pts) is an anthropometric measures that varies with states of health Compare the skinfold thickness of 5 men with Chronic Lung Disease to a Control group Create a 5 Number Summary and a Boxplot of the two skinfold thickness measurements Lung Dis Control 5-Number Summary 9.1 10.4 Lung Control 10.9 19.6 Max 11.4 20.6 03 15.3 23.8 Median 18.4 24.7 Q1 32.8 Min Mean Std.
