Marked out of 1.00 We measured the longitudinal diameter of 400 red blood cells in a microscope. The mean of the diameters is \( 24.8 \mu \mathrm{m} \) and the calculated reference interval is \( 20.8-28.8 \mu \mathrm{m} \). Calculate the standard deviation of the data in units of \( \mu \mathrm{m} \) !

Step 1
This means that approximately 95% of the data falls within this range. Given that the mean is 24.8 µm, and the reference interval is 20.8-28.8 µm, we can calculate the standard deviation as follows: Show more…

Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a standard deviation of 0.382 million cells per microliter. Find the 80 th percentile for the red blood cell counts of women.

Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a standard deviation of 0.382 million cells per microliter. Find the value closest to the probability that a randomly selected woman has a red blood cell count above the normal range of 4.2 to 5.4 million cells per microliter.

Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a standard deviation of 0.382 million cells per microliter. Approximately what percentage of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter?
