Chapter 7: Q.58 (page 455)

The CLT applet Go to the textbook Web site (www whfreeman com/tp4e) and click on "Statistical Applets." Launch the Central limit Theorem applet. You should see a screen like the one shown here. Click and drag the slider to change the sample size, and watch how the density curve for the sampling distribution changes with it. Write a few sentences describing what in happening.

Short Answer

Expert verified

The population distribution in the applet is right-skewed.

Step by step solution

01

Step-1 Given Information

Given in the question that

we have to Click and drag the slider to change the sample size, and watch how the density curve for the sampling distribution changes with with it.

02

Step-2 Explanation

The sample mean sampling distribution is represented by the applet.

The population distribution in the applet is shown to be right-skewed.

The sampling distribution becomes increasingly bell-shaped and the distribution becomes normal as the sample size increases. In addition, if the sample size is small, the sampling distribution will have the same right skewness as the population distribution.

As a result, the applet's population distribution is right-skewed.

AP2.22. A health worker is interested in determining if omega-3fish oil can help reduce cholesterol in adults. She obtains permission to examine the health records of200 people in a large medical clinic and classifies them
according to whether or not they take omega-3fish oil. She also obtains their latest cholesterol readings and finds that the mean cholesterol reading for those who are taking omega-3fish oil is 18points lower than the mean for the group not taking omega-3 fish oil.
(a) Is this an observational study or an experiment? Explain.
(b) Do these results provide convincing evidence that taking omega-3 fish oil lowers cholesterol?
(c) Explain the concept of confounding in the context of this study and give one example of a possible confounding variable.

On Tuesday, the bottles of Arizona Iced Tea filled in a plant were supposed to contain an average of 20ounces of iced tea. Quality control inspectors sampled50bottles at random from the day鈥檚 production. These bottles contained an average of 20ounces of iced tea.

Unlisted numbers: A telemarketing firm in Los Angeles uses a device that dials residential telephone numbers in that city at random. Of the first 100numbers dialed, 48%are unlisted. This is not surprising because 52%of all Los Angeles residential phones are unlisted.

A machine is designed to fill 16-ounce bottles of shampoo. When the machine is working properly, the mean amount poured into the bottles is 16.05ounces with a standard deviation of 0.1ounces. Assume that the machine is working properly. If four bottles are randomly selected each hour and the number of ounces in each bottle is measured, then 95%of the observations should occur in which interval?

(a) 16.05to 16.15ounces

(b) 0.30to 0.30ounces

(c) 15.95to16.15 ounces

(d) 15.90to 16.20ounces

(e) None of the above

Mars, Incorporated, says that the mix of colors in its M&M鈥橲庐 Milk Chocolate Candies is 24%blue, 20%orange, 16%green,14%yellow, 13%red, and 13%brown. Assume that the company鈥檚 claim is true. We want to examine the proportion of orange M&M鈥橲 in repeated random samples of 50candies. Which of the graphs that follow could be the approximate sampling distribution of the statistic?
