Chapter 3.2, Problem 1AC

Blood Pressure

The table lists means and standard deviations. The mean is the number before the plus/minus, and the standard deviation is the number after the plus/minus. The results are from a study attempting to find the average blood pressure of older adults. Use the results to answer the questions.

Chapter 3.2, Problem 1AC, Blood Pressure The table lists means and standard deviations. The mean is the number before the

1. Apply Chebyshev’s theorem to the systolic blood pressure of normotensive men. At least how many of the men in the study fall within 1 standard deviation of the mean?

2. At least how many of those men in the study fall within 2 standard deviations of the mean?

3. Assume that blood pressure is normally distributed among older adults. Answer the following questions, using the empirical rule instead of Chebyshev’s theorem.

What are the ranges for the diastolic blood pressure (normotensive and hypertensive) of older women?

4. Do the normotensive, male, systolic blood pressure ranges overlap with the hypertensive, male, systolic blood pressure ranges?
