The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 263.8 and a standard deviation of 69.3. (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 2 standard deviations of the mean, or between 125.2 and 402.4? b. What is the approximate percentage of women with platelet counts between 55.9 and 471.7? C a. Approximately 95% of women in this group have platelet counts within 2 standard deviations of the mean, or between 125.2 and 402.4. (Type an integer or a decimal. Do not round.) b. Approximately % of women in this group have platelet counts between 55.9 and 471.7. (Type an integer or a decimal. Do not round.)
