Interpreting Normal Quantile Plots.In Exercises 5鈥�8, examine the normal quantile plot and determine whether the sample data appear to be from a population with a normal distribution.

Diet Pepsi The normal quantile plot represents weights (pounds) of the contents of cans of Diet Pepsi from Data Set 26 鈥淐ola Weights and Volumes鈥� in Appendix B.

Short Answer

Expert verified

From the given normal quantile plot, it appears that the sample data of weights(pounds) of the contents of cans of Diet Pepsi is from a population that follows the normal distribution because the points on the plot follow a straight line pattern.

Step by step solution

01

Given information

The normal quantile plot of the sample data of weights (pounds) of the contents of cans of Diet Pepsi is constructed.

02

Step 2:Interpretation of the normal quantile plot

In a normal quantile plot, if the points form a straight-line pattern, then the sample is said to be taken from a normally distributed population.

Here, the points on the plot lie close to the straight line.

Therefore, the sample ofweights (pounds) of the contents of cans of Diet Pepsi appears to be from a normally distributed population.

Basis for the Range Rule of Thumb and the Empirical Rule. In Exercises 45鈥�48, find the indicated area under the curve of the standard normal distribution; then convert it to a percentage and fill in the blank. The results form the basis for the range rule of thumb and the empirical rule introduced in Section 3-2.

About______ % of the area is between z = -3 and z = 3 (or within 3 standard deviation of the mean).

In Exercises 5鈥�8, find the area of the shaded region. 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).

Water Taxi SafetyWhen a water taxi sank in Baltimore鈥檚 Inner Harbor, an investigation revealed that the safe passenger load for the water taxi was 3500 lb. It was also noted that the mean weight of a passenger was assumed to be 140 lb. Assume a 鈥渨orst-case鈥� scenario in which all of

the passengers are adult men. Assume that weights of men are normally distributed with a mean of 188.6 lb and a standard deviation of 38.9 lb (based on Data Set 1 鈥淏ody Data鈥� in Appendix B).

a. If one man is randomly selected, find the probability that he weighs less than 174 lb (the new value suggested by the National Transportation and Safety Board).

b. With a load limit of 3500 lb, how many male passengers are allowed if we assume a mean weight of 140 lb?

c. With a load limit of 3500 lb, how many male passengers are allowed if we assume the updated mean weight of 188.6 lb?

d. Why is it necessary to periodically review and revise the number of passengers that are allowed to board?

Standard Normal DistributionIn Exercises 17鈥�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.

Greater than 0.25

Body Temperatures Based on the sample results in Data Set 3 鈥淏ody Temperatures鈥� in Appendix B, assume that human body temperatures are normally distributed with a mean of 98.20掳F and a standard deviation of 0.62掳F.

a. According to emedicinehealth.com, a body temperature of 100.4掳F or above is considered to be a fever. What percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.4掳F is appropriate?

b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 2.0% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.)
