The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 254.4 and a standard deviation of 61.1. (All units are 1000 cells/µL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 193.3 and 315.5? b. What is the approximate percentage of women with platelet counts between 71.1 and 437.7? ...
