10. Finding scores, z-scores and percentages corresponding to specific z-scores Tai chi exercise may reduce blood pressure (BP) and serve as a practical, nonpharmacological adjunct to conventional hypertension management. A geriatric psychologist is interested in studying nonpharmacological approaches for senior citizens struggling with prehypertension. Systolic blood pressure scores for senior citizens follow a normal distribution with u = 110 and o = 21. Use the Distributions tool to help answer the questions that follow. Note: To find the probability above or below a z-score, click on the normal curve icon with one line, and position the line at the appropriate z-score on the horizontal axis. The areas under the standard normal curve above and below the z-score will be displayed to the left and right of the vertical line, respectively. To find the probability between two z-scores, click on the normal curve icon with two lines, and position the left line at the lower z-score and the right line at the higher z-score. The area under the normal curve between the vertical lines will be displayed in blue. Standard Normal Distribution Mean = 0.0 Standard Deviation = 1.0 -3 -2 -1 .5000 .5000 0 0.000 1 3
