The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 250.6 and a standard deviation of 69.5. (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 3 standard deviations of the mean, or between 42.1 and 459.1? b. what is the approximate percentage of women with platelet counts between 111.6 and 389.6?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

whatvare the choices
