The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 256.9 and a standard deviation of 63.6. (All units are 1000 cells/μL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 66.1 and 447.7? b. What is the approximate percentage of women with platelet counts between 193.3 and 320.5? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 66.1 and 447.7. (Type an integer or a decimal. Do not round.)
