What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 188.5 and 326.9? b. What is the approximate percentage of women with platelet counts between 50 1 and 465 3? a. Approximately % of women in this group have platelet counts within 1 standard deviation of the mean, or between 188 5 and 326.9. (Type an integer or a decimal. Do not round.)
