The average number of red blood cells per cubic mm in humans is about 5 million. We'll let μ = 5,000,000, and σ = 500,000. Let's also assume that the number of red blood cells follows a normal distribution.
a) Give the values for the number of red blood cells for the middle 80% of people. (Hint/comment: if, for example, you want values for the middle 50%, you need to figure out many percent go in each tail. Note also that you will need two numbers in your answer. Draw a picture to help you.)
b) Give the values for the number of red blood cells for the middle 98% of people.
c) Give the 99th percentile.
d) Are you surprised by the answers to (b) and (c)? Explain. If you're not sure what's going on, draw some pictures of the normal curves.
e) Calculate the 1st percentile.
