The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 259.1 and a standard deviation of 60.1. (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 2 standard deviations of the mean, or between 138.9 and 379.3? b. What is the approximate percentage of women with platelet counts between 78 8 and 439.4? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 138 9 and 379.3. (Type an integer or a decimal. Do not round) b. Approximately % of women in this group have platelet counts between 78.8 and 439 4. (Type an integer or a decimal. Do not round)
