The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 252.2 and a standard deviation of 62.9. (All units are 1000 cells/jL.) 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 63.5 and 440.9? b. What is the approximate percentage of women with platelet counts between 189.3 and 315.1? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 63.5 and 440.9. (Type an integer or a decimal. Do not round.) b. Approximately |% of women in this group have platelet counts between 189.3 and 315.1. (Type an integer or a decimal. Do not round.) Next
