L The blood platelet counts of a group of women have a bell-shaped oot 4 distribution with a mean of 258.1 and a standard deviation of 61.6. (All units are 1000 cells/pL.) 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 73.3 and 442 .97 b. What is the approximate percentage of women with platelet counts between 134.9 and 381.3? a. Approximately D% of women in this group have platelet counts within 3 standard deviations of the mean, or between 73.3 and 442.9. (Type an integer or a decimal. Do not round.) b. Approximately D% of women in this group have platelet counts between 134.9 and 381.3. (Type an integer or a decimal. Do not round.)
