The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 257.1 and a standard deviation of 63.2. (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 130.7 and 383.57 b. What is the approximate percentage of women with platelet counts between 67.5 and 446.77 a. Approximately% of women in this group have platelet counts within 2 standard deviations of the mean, or between 130.7 and 383.5. (Type an integer or a decimal. Do not round.)
