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 5.7 million cells per microliter and a standard deviation of 0.4 million cells per microliter. (a) What is the minimum red blood cell count that can be in the top 20% of counts? (b) What is the maximum red blood cell count that can be in the bottom 10% of counts? (a) The minimum red blood cell count is million cells per microliter. (Round to two decimal places as needed.) (b) The maximum red blood cell count is million cells per microliter (Round to two decimal places as needed.)
