Chapter 6: Q1 (page 281)

Normal Quantile Plot Data Set 1 “Body Data” in Appendix B includes the heights of 147 randomly selected women, and heights of women are normally distributed. If you were to construct a histogram of the 147 heights of women in Data Set 1, what shape do you expect the histogram to have? If you were to construct a normal quantile plot of those same heights, what pattern would you expect to see in the graph?

Short Answer

Expert verified

The histogram of the 147 heights would be bell-shaped.

The normal quantile plot of the heights of 147 women will have points that follow a straight-line pattern.

Step by step solution

01

Given information

The heights of 147 women are normally distributed.

02

Shape of the normal distribution

When a set of data that is normally distributed is plotted on a histogram, the histogram is bell-shaped.

Here, the heights of women are normally distributed.

Thus, the histogram of the 147 heights would be bell-shaped.

03

Pattern of normal quantile plot

If a set of data that is normally distributed is plotted on a normal quantile plot, the points on the plot follow a straight-line pattern.

Here, the normal quantile plot of the heights of 147 women will have points that follow a straight-line pattern.

In Exercises 13–20, 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.)

Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if P(x or greater) ≤ 0.01 and a value is significantly low if P(x or less) ≤ 0.01. Find the back-to-knee lengths for males, separating significant values from those that are not significant. Using these criteria, is a male back-to-knee length of 26 in. significantly high?

Standard Normal DistributionIn Exercises 17–36, assume that a randomly selected subject is given a bone density test. Those 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 probability of the given bone density test scores. If using technology instead of Table A-2, round answers

to four decimal places.

Births There are about 11,000 births each day in the United States, and the proportion of boys born in the United States is 0.512. Assume that each day, 100 births are randomly selected and the proportion of boys is recorded.

a. What do you know about the mean of the sample proportions?

b. What do youknow about the shape of the distribution of the sample proportions?

Standard normal distribution, assume that a randomly selected subject is given a bone density test. Those 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 probability of the given bone density test score. If using technology instead of Table A-2, round answers to four decimal places.
