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.

In gene transfer, researchers introduce a foreign gene directly into cancer cells or into surrounding tissue. The goal is that the newly inserted gene will cause the cancer cells to die or prevent cancer cells and surrounding tissue from funneling blood to tumors, depriving them of nutrients they need for survival.

A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35
Mazyrski [523]
<span>The labs were unable to reproduce the pharmaceutical company’s data

An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
