Extracted text: The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 260.5 and a standard deviation of 66.9. (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 126.7 and 394.3? b. What is the approximate percentage of women with platelet counts between 193.6 and 327.4? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 126.7 and 394.3. (Type an integer or a decimal. Do not round.)
