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 22% of counts? (b) What is the maximum red blood cell count that can be in the bottom 16% of counts? The weights of bags of baby carrots are normally distributed, with a mean of 31 ounces and a standard deviation of 0.39 ounce. Bags in the upper 4.5% are too heavy and must be repackaged. What is the most a bag of baby carrots can weigh and not need to be repackaged? Click here to view Page 1 of the Standard Normal Table. Click here to view Page 2 of the Standard Normal Table. A bag of baby carrots can weigh at most I] ounces without needing to be repackaged. (Round to two decimal places as needed.)
