Chapter 6: Q10 (page 292)

In Exercises 6鈥�10, assume that women have diastolic blood pressure measures that are normally distributed with a mean of 70.2 mm Hg and a standard deviation of 11.2 mm Hg (based on Data Set 1 鈥淏ody Data鈥� in Appendix B).

Diastolic Blood Pressure The accompanying normal quantile plot was constructed from the diastolic blood pressure levels of a sample of women. What does this graph suggest about diastolic blood pressure levels of women?

Short Answer

Expert verified

The diastolic blood pressure levels of women are normally distributed.

Step by step solution

01

Given information

A normal quartile plot for the blood pressure levels of women is given.

02

Define a normality plot

A normality plot is a graph for paired observed values and corresponding z scores.

If the dots of the graph fall on a straight-line pattern, the data can be concluded to have been originated from the normal distribution.

03

Identify the normal pattern in the normality plot

The pattern of points in the given normal probability plot falls on a straight line (linear). Thus, this suggests that the diastolic blood pressure levels of women are normally distributed.

Most popular questions from this chapter

In Exercises 9鈥�12, find the indicated IQ score and round to the nearest whole number. The graphs depict IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler IQ test).

Random Digits Computers are commonly used to randomly generate digits of telephone numbers to be called when conducting a survey. Can the methods of this section be used to find the probability that when one digit is randomly generated, it is less than 3? Why or why not? What is the probability of getting a digit less than 3?

Finding Bone Density Scores. In Exercises 37鈥�40 assume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. In each case, draw a graph, then find the bone density test score corresponding to the given information. Round results to two decimal places.

If bone density scores in the bottom 2% and the top 2% are used as cutoff points for levels that are too low or too high, find the two readings that are cutoff values.

Low Birth Weight The University of Maryland Medical Center considers 鈥渓ow birth weights鈥� to be those that are less than 5.5 lb or 2495 g. Birth weights are normally distributed with a mean of 3152.0 g and a standard deviation of 693.4 g (based on Data Set 4 鈥淏irths鈥� in Appendix B).

a. If a birth weight is randomly selected, what is the probability that it is a 鈥渓ow birth weight鈥�?

b. Find the weights considered to be significantly low, using the criterion of a birth weight having a probability of 0.05 or less.

c. Compare the results from parts (a) and (b).

In Exercises 13鈥�20, use the data in the table below for sitting adult males and females (based on anthropometric survey data from Gordon, Churchill, et al.). These data are used often in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. (Hint: Draw a graph in each case.)
