Find the probability that a randomly selected woman has a red blood count is less than 4.2. Round to 4 decimals. [a1] b. Find the probability that a randomly selected woman has a red blood count is greater than 5.4. Round to 4 decimals.  [a2] c. Find P80, the 80th percentile for the red blood cell counts of women. Round to three decimal places.  [a3] d. If 25 women are randomly selected, find the probability that the mean of their red blood cell counts is less than 4.444. Round to 4 decimals. [a4] e. What percentage of women have red blood cell counts in the normal range between 4.2 and 5.4? Round to one tenth of a percent. [a5]
