The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 255.3 and a standard deviation of 61.2. (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 132.9 and 377.7? b. What is the approximate percentage of women with platelet counts between 194.1 and 316.5? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 132.9 and 377,7 (Type an integer or a decimal. Do not round.) b. Approximately % of women in this group have platelet counts between 194.1 and 316.5. (Type an integer or a decimal. Do not round.)
