The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean µ = 125 and standard deviation σ = 14. Systolic blood pressure for males follows a normal distribution. Calculate the z-scores for the male systolic blood pressures 100 and 150 millimeters. z-score for 100 = z-score for 150 =

Step 1
First, we need to remember the formula for calculating a z-score: z = (X - µ) / σ where: X = value from the dataset µ = mean of the dataset σ = standard deviation of the dataset For a systolic blood pressure of 100 millimeters, we substitute into the formula: Show more…

The systolic blood pressure (in millimeters) of males has an approximately normal distribution with mean μ = 125 and standard deviation σ = 14. Find the 80th percentile of the distribution of systolic blood pressures. Round to the nearest whole number.

The average systolic blood pressure of a population of young men is population mean = 112.5 mm, population standard deviation = 16.4 mm. Prehypertension is defined as having a systolic pressure between 120 and 139. Calculate the z-score for a systolic pressure of 120.
