Assume that women have diastolic blood pressure measures that are normally distributed with a mean of 70.2 mm Hg and a standard deviation of 11.2 mm Hg (based on Data Set 1 “Body Data” in Appendix B). Find the probability that a randomly selected woman has a normal diastolic blood pressure level, which is below 80 mm Hg. Find the probability that a randomly selected woman has a diastolic blood pressure level between 60 mm Hg and 80 mm Hg. Find P90, the 90th percentile for the diastolic blood pressure levels of women.

Question

Assume that women have diastolic blood pressure measures that are normally distributed with a mean of 70.2 mm Hg and a standard deviation of 11.2 mm Hg (based on Data Set 1 “Body Data” in Appendix B).

  1. Find the probability that a randomly selected woman has a normal diastolic blood pressure level, which is below 80 mm Hg.
  2. Find the probability that a randomly selected woman has a diastolic blood pressure level between 60 mm Hg and 80 mm Hg.
  3. Find P90, the 90th percentile for the diastolic blood pressure levels of women.
  4. If 16 women are randomly selected, find the probability that the mean of their diastolic blood pressure levels is less than 75 mm Hg.
  5. The accompanying normal quantile plot was constructed from the diastolic blood pressure levels of a sample of women. What does this graph suggest about diastolic blood pressure levels of women?
