The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 250.2 and a standard deviation of 69.2. (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 111.8 and 388.6? b. What is the approximate percentage of women with platelet counts between 42.6 and 457.8? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 111.8 and 388.6. (Type an integer or a decimal. Do not round.)
