Chapter 2: Q 79. (page 142)

Runners鈥� heart rates The following figure is a Normal probability plot of the heart rates of 200male runners after 6 minutes of exercise on a treadmill.14 Use the graph to determine if this distribution of heart rates is approximately Normal.

Short Answer

Expert verified

Yes, it is not approximately normal.

Step by step solution

01

Given information

The figure is:

02

Concept

The distance between the minimum and maximum values from the mean must be the same for the distribution to be normal.

03

Explanation

The data points in the presented picture follow a linear trend, and there is no curvature in the normal probability plot, as can be seen. Furthermore, the data points form a relatively straight line. As a result, the distribution of heart rates can be described as approximately normal.

Measuring bone density Individuals with low bone density (osteoporosis) have a high risk of broken bones (fractures). Physicians who are concerned about low bone density in patients can refer them for specialized testing. Currently, the most common method for testing bone density is dual-energy X-ray absorptiometry (DEXA). The bone density results for a patient who undergoes a DEXA test usually are reported in grams per square centimeter (g/cm2) and in standardized units. Judy, who is 25years old, has her bone density measured using DEXA. Her results indicate bone density in the hip of 948 g/cm2 and a standardized score of z=鈭�1.45The mean bone density in the hip is 956 g/cm2in the reference population of 25-year-old women like Judy.

a. Judy has not taken a statistics class in a few years. Explain to her in simple language what the standardized score reveals about her bone density.

b. Use the information provided to calculate the standard deviation of bone density in the reference population.
