23. The blood platelet counts ofa group of women have a bell-shaped distribution with a mean of 245.3 and a standard deviation of 32.5. {All units are 1333 cellslpLJ Using the empirical rule, find each approximate percentage below. a. 1il'v'hat is the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 53.3 and 433.3\"?I b. 1il'v'hat is the approximate percentage of women with platelet counts between 133.3 and 333.3? a. Approximately :33 of women in this group have platelet counts within 3 standard deviations of the mean, or between 53.3 and 433.3. [Type an integer or a decimal. Do not round.) b. Approximately :33 of women in this group have platelet counts between 133.3 and 333.3. (Type an integer or a decimal. Do not round.) 28. A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation. Systolic 119 126 160 97 154 123 116 138 124 118 Diastolic 78 75 75 50 88 89 60 71 82 The coefficient of variation for the systolic measurements is (Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the diastolic measurements is (Type an integer or decimal rounded to one decimal place as needed.) Compare the variation. The coefficients of variation for each data set are (1) Therefore, the systolic measurements vary (2) the diastolic measurements. (1) O more than 5 percentage points apart. (2) O significantly less than O within 5 percentage points of each other. O significantly more than O about the same as
