Using the empirical rule, nd each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 128.8 and 380.0? b. What is the approximate percentage of women with platelet counts between 66.0 and 442.8? E) a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean. or between 128.8 and 380.0. (Type an integer or a decimal. Do not round.) b.Approximately % of women in this group have platelet counts between 66.0 and 442.8. (Type an integer or a decimal. Do not round.)
