The pregnancy length in days for a population of new mothers can be approximated by a normal distribution with a mean of 267 days and a standard deviation of 10 days. (a) What is the minimum pregnancy length that can be in the top 10% of pregnancy lengths? (b) What is the maximum pregnancy length that can be in the bottom 7% of pregnancy lengths? (a) The minimum pregnancy length is |days. (Round to one decimal place as needed.) 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 5.1 million cells 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 28% of counts? (b) What is the maximum red blood cell count that can be in the bottom 16% of counts? (a) The minimum red blood cell count is million cells per microliter. Round to two decimal places as needed.) The test scores for the analytical writing section of a particular standardized test can be Q approximated by a normal distribution, as shown in the figure. (a) What is the maximum score that can be in the bottom 20% of scores? (b) Between what two values does the middle 60% of scores lie? H = 3.5 G=0.89 3.5 6 Score (a) The maximum score that can be in the bottom 20% is. (Round to two decimal places as needed.)
