The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 262.2 and a standard deviation of 61.4. (All units are 1000 cells/uL.) 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 78.0 and 446.4? b. What is the approximate percentage of women with platelet counts between 200.8 and 323.6? a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or between 78.0 and 446.4. (Type an integer or a decimal. Do not round.) b. Approximately % of women in this group have platelet counts between 200.8 and 323.6. (Type an integer or a decimal. Do not round.)

deviation of 61.4. (All units are 1000 cells/uL.) 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 78.0 and 446.4?
b. What is the approximate percentage of women with platelet counts between 200.8 and 323.6?
a. Approximately % of women in this group have platelet counts within 3 standard deviations of the mean, or
between 78.0 and 446.4.
(Type an integer or a decimal. Do not round.)
b. Approximately % of women in this group have platelet counts between 200.8 and 323.6.
