Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a

postnew [5]

Answer: C. 82.26%

Explanation:

Given : The red blood cell counts of women are normally distributed with

$\mu=4.577\text{ million cells per microliter}$

$\sigma=0.382\text{ million cells per microliter}$

Let X be the random variable that represents the red blood cell counts of randomly selected woman.

Z-score : $z=\dfrac{X-\mu}{\sigma}$

For X=4.2

$z=\dfrac{4.2-4.577}{0.382}\approx-0.99$

For X=5.4

$z=\dfrac{5.4-4.577}{0.382}\approx2.1544$

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-

$P(4.2$

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.
