The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 251.5 and a standard deviation of 69.1. (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 44.2 and 458.87 b. What is the approximate percentage of women with platelet counts between 113.3 and 389.7? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 44.2 and 458.8. (Type an integer or a decimal. Do not round.) b. Approximately% of women in this group have platelet counts between 113.3 and 389.7. (Type an integer or a decimal. Do not round.)
