Chapter 11: Q 8. (page 716)

No chi-square The principal in Exercise 7 also asked the random sample of students to record whether they did all of the homework that was assigned on each of the five school days that week. Here are the data:

Short Answer

Expert verified

Because the observations are not independent, a chi-square test for goodness of fit is not appropriate.

Step by step solution

01

Given information

02

Explanation

The observations must be independent in order to use the chi-square test for goodness of fit. Because most kids will have the same teachers, independent observations are not possible. As a result, a chi-square test for goodness of fit would be inappropriate.

Birds in the trees Researchers studied the behavior of birds that were searching for seeds and insects in an Oregon forest. In this forest, 54% of the trees are Douglas firs, 40% are ponderosa pines, and 6% are other types of trees. At a randomly selected time during the day, the researchers observed 156 red-breasted nuthatches: 70 were seen in Douglas firs, 79 in ponderosa pines, and 7 in other types of trees.

a. Do these data provide convincing evidence that nuthatches prefer particular types of trees when they鈥檙e searching for seeds and insects?

b. Relative to the proportion of each tree type in the forest, which type of trees do the nuthatches seem to prefer the most? The least?

A Type I error would occur if we found convincing evidence that

a. HCC wiring caused cancer when it actually didn鈥檛.

b. HCC wiring didn鈥檛 cause cancer when it actually did.

c. there is no association between the type of wiring and the form of cancer when there actually is an association.

d. there is an association between the type of wiring and the form of cancer when there actually is no association.

e. the type of wiring and the form of cancer have a positive correlation when they actually don鈥檛.

Fewer TVs? The United States Energy Information Administration periodically surveys a random sample of U.S. households to determine how they use energy. One of the variables they track is how many TVs are in a household (None, 1,2,3,4,or5or more). The computer output compares the distribution of number of TVs for households in 2009and2015.

Chi-Squarerole="math" localid="1654195309908" =137.137, DF =5, P-Value =0.000

a. Which chi-square test is appropriate to analyze these data? Explain your answer.

b. Show how the numbers 252and 14.113were obtained for the 2009/Nonecell.

c. Which 3cells contribute most to the chi-square test statistic? How do the observed and expected counts compare for these cells?

Treating ulcers Gastric freezing was once a recommended treatment for ulcers in the upper intestine. Use of gastric freezing stopped after experiments showed it had no effect. One randomized comparative experiment found that28of the 82gastric-freezing patients improved, while 30of the 78patients in the placebo group improved. We can test the hypothesis of 鈥渘o difference鈥� in the effectiveness of the treatments in two ways: with a two-sample z test or with a chi-square test.

a. State appropriate hypotheses for a chi-square test.

b. Here is Minitab output for a chi-square test. Interpret the P-value. What conclusion would you draw?

c. Here is Minitab output for a two-sample z test. Explain how these results are consistent with the test in part (a).

A random sample of traffic tickets given to motorists in a large city is examined. The tickets are classified according to the race or ethnicity of the driver. The results are summarized in the following table.

The proportion of this city's population in each of the racial/ethnic categories listed is as follows.

We wish to test H0: The racial/ethnic distribution of traffic tickets in the city is the same as the racial/ethnic distribution of the city's population.

We compute the value of the 蠂2test statistic to be 6.57. Assuming that the conditions for inference are met, which of the following is the correct P-value?

a. Greater than0.20

b. Between 0.10and0.20

c. Between 0.05and0.10

d. Between 0.01and0.05

e. Less than0.01
