A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?

7250 WBC/ml

Explanation:

The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us

10,000 + 4,500 = 14,500 WBC/ml

The mean then is

14,500 / 2 = 7250 WBC/ml

Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml

yes, because even though a theory has a  lot of evidence to support it, it is not always true
