6.33 White Blood Cells The distribution of white blood cell counts per cubic millimeter of whole blood is approximately Normal with mean 7500 and standard deviation 1750 for healthy patients. Use technology or a table to answer these questions. For each include an appropriately labeled and shaded Normal curve. a. What is the probability that a randomly selected person will have a white blood cell count between 6000 and 10,000?b. An elevated white blood cell count can be a sign of infection some-where in the body. A white blood cell count can be considered elevated if it is over 10,500. What percentage of people have white blood cell counts in this elevated range?c. A white blood cell count below 4500 is considered low. People in this range may be referred for additional medical testing. What is the prob-ability that a randomly selected person has a white blood cell count below 4500?
