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.
