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 5.2 million ocells per microliter and a standard deviation of 0.5 million cells per microliter. (a) What is the minimum red blood cell count that can be in the top 30% of counts? (b) What is the maximum red blood cell count that can be in the bottom 15% of counts? (a) The minimum red blood cell count is million cells per microliter. (Round to two decimal places as needed.)
