Question: Red Blood Cell Count Use the normal distribution in Exercise 16. (a) What percent of the adult males have a red blood cell count less

Red Blood Cell Count Use the normal distribution in Exercise 16.

(a) What percent of the adult males have a red blood cell count less than 5.75 million cells per microliter?

(b) What percent of the adult males have a red blood cell count between 4.75 and 5.25 million cells per microliter?

(c) Out of 500 randomly selected adult males, about how many would you expect to have a red blood cell count greater than 5.0 million cells per microliter?

Answer the questions about the specified normal distribution.
