The average systolic blood pressure of a population of young men is u = 112.5 mm, o = 16.4 mm. Prehypertension is defined as having a systolic pressure between 120 and 139. 2. Calculate the z-score for a systolic pressure of 139. 3. What is the probability that you could randomly select a young man from the population that would have an average systolic pressure greater than 139? 4. What is the probability that you could randomly select a young man from the population that would be diagnosed with having prehypertension (systolic pressure between 120 and 139)?
