The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 249.2 and a standard deviation of 68.5. (All units are 1000 cells/UL) 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 43.7 and 454. 7? b. What is the approximate percentage of women with platelet counts between 112.2 and 386.2? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 43 7 and 454.7 st (Type an integer or a decimal. Do not round.)
