The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 253.6 and a standard deviation of 67.7. (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 1 standard deviation of the mean, or between 185.9 and 321.3? b. What is the approximate percentage of women with platelet counts between 50.5 and 456.7? a. Approximately% of women in this group have platelet counts within 1 standard deviation of the mean, or between 185.9 and 321.3. (Type an integer or a decimal. Do not round.)
