Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.48 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are greater than 11.52? Please do not round your answer.
here as z score =(X-mean)/std deviation
therfore percentage of American women have shoe sizes that are greater than 11.52 =P(X>11.52)
=P(Z>(11.52-8.48)/1.52)=P(Z>2) =2.5%

The blood platelet counts of a
group of women have a bell-shaped distribution with a mean of
256.5 and a standard deviation of 68.2. (All units are 1000
cells/muL.) Using the empirical rule, find each approximate
percentage below. a. What is the approximate percentage of women
with platelet counts within 2 standard deviations of the mean, or
between 120.1 and 392.9? b. What is the approximate percentage of
women with platelet counts between 51.9 and 461.1?
The blood platelet counts...
