The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 259.1 and a standard deviation of 68.2. (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 3 standard deviations of the mean, or between 54.5 and 463.77
b. What is the approximate percentage of women with platelet counts between 122.7 and 395.5?
a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 54.5 and 463.7
(Type an integer or a decimal. Do not round.)
