Detailed explanation-1: -The minimum red blood cell count that can be in the top 27% of counts is 6.2 million cells per microliter. The maximum red blood cell count that can be in the bottom 12% of counts is 8.8 million cells per microliter.
Detailed explanation-2: -In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.
Detailed explanation-3: -A normal RBC count would be around: men – 4.0 to 5.9 x 10*12/L. women – 3.8 to 5.2 x 10*12/L.
Detailed explanation-4: -The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a normal distribution, with a mean of 5.4 million cells per microliter and a standard deviation of 0.4 million cells per microliter.
