Chapter 11: Q. T11.13 (page 765)

In the United States, there is a strong relationship between education and smoking: well-educated people are less likely to smoke. Does a similar relationship hold in France? To find out, researchers recorded the level of education and smoking status of a random sample of 459French men aged 20to60years. The two-way table displays the data.

Is there convincing evidence of an association between smoking status and educational level among French men aged20to60years?

Short Answer

Expert verified

There is convincing evidence that there is association between education and smoking status.

Step by step solution

01

Step 1. Given information

Given:

02

Step 2. Explanation

The null and alternative hypotheses:

H0: There is no association between education and smoking status.

Ha: There is association between education and smoking status.

Using excel,

Chi-square test statistic =13.30. The degrees of freedom =6and p-value =0.0384

Decision: P-value<0.05, reject H0.

Conclusion: There is convincing evidence that there is association between education and smoking status.

A study conducted in Charlotte, North Carolina, tested the effectiveness of three police responses to spouse abuse: (1)advise and possibly separate the couple, (2)issue a citation to the offender, and (3)arrest the offender. Police officers were trained to recognize eligible cases. When presented with an eligible case, a police officer called the dispatcher, who would randomly assign one of the three available treatments to be administered. There were a total of 650cases in the study. Each case was classified according to whether the abuser was arrested within 6months of the original incident.

a. Explain the purpose of the random assignment in the design of this study.

b. State an appropriate pair of hypotheses for performing a chi-square test in this setting.

c. Assume that all the conditions for performing the test in part (b) are met. The test yields x2=5.063x2=5.063and aP-valueof0.0796. Interpret this P-value.

d. What conclusion should we draw from the study?

Tuition bills A random sample of U.S. adults was recently asked, 鈥淲ould you support or oppose major new spending by the federal government that would help undergraduates pay tuition at public colleges without needing loans?鈥� The two-way table shows the responses, grouped by age.

Do these data provide convincing evidence of an association between age and opinion about loan-free tuition in the population of U.S. adults?

How to quit smoking Refer to Exercise 37. Which treatment seems to be most effective? Least effective? Justify your choices.

Munching Froot Loops Kellogg鈥檚 Froot Loops cereal comes in six colors:

orange, yellow, purple, red, blue, and green. Charise randomly selected 120 loops and noted the color of each. Here are her data:

Do these data provide convincing evidence at the 5% significance level that Kellogg鈥檚 Froot Loops do not contain an equal proportion of each color?

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.
