Chapter 11: Q. 55 (page 758)

The National Longitudinal Study of Adolescent Health interviewed a random sample of 4877teens (grades 7to 12). One question asked, 鈥淲hat do you think are the chances you will be married in the next 10years?鈥� Here is a two-way table of the responses by gender:

Which of the following is the appropriate null hypothesis for performing a chi-square test?

a. Equal proportions of female and male teenagers are almost certain they will be married in 10years.

b. There is no difference between the distributions of female and male teenagers鈥� opinions about marriage in this sample.

c. There is no difference between the distributions of female and male teenagers鈥� opinions about marriage in the population.

d. There is no association between gender and opinion about marriage in the sample.

e. There is no association between gender and opinion about marriage in the population.

Short Answer

Expert verified
Option (e)Ho: There is no correlation between gender and population opinion on marriage.
Ha: In the population, there is a link between gender and attitudes toward marriage.

Step by step solution

01

Given information

We have to determine the state the null and alternative hypotheses.

02

Simplification

The null and alternative hypotheses:

鈥冣赌�H0: There is no correlation between gender and population opinion on marriage.

鈥冣赌�Ha: In the population, there is a link between gender and attitudes toward marriage.

Hence, option e is correct.

All current-carrying wires produce electromagnetic (EM) radiation, including the electrical wiring running into, through, and out of our homes. High-frequency EM radiation is thought to be a cause of cancer. The lower frequencies associated with household current are generally assumed to be harmless. To investigate the relationship between current configuration and type of cancer, researchers visited the addresses of a random sample of children who had died of some form of cancer (leukemia, lymphoma, or some other type) and classified the wiring configuration outside the dwelling as either a high-current configuration (HCC) or a low-current configuration (LCC). Here are the data:

Computer software was used to analyze the data. The output included the value X2=0.435

Which of the following is the appropriate degrees of freedom for the X2test?

a. 1

b. 2

c. 3

d. 4

e. 5

Last candy Refer to Exercises 27 and 29.

a. Verify that the conditions for inference are met.

b. Use Table C to find the P-value. Then use your calculator鈥檚 蠂2 cdf command.

c. Interpret the P-value from the calculator.

d. What conclusion would you draw using 伪=0.01?

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

Is astrology scientific? The General Social Survey (GSS) asked a random sample of adults their opinion about whether astrology is very scientific, sort of scientific, or not at all scientific. Here is a two-way table of counts for people in the sample who had three levels of higher education:

a. State appropriate hypotheses for performing a chi-square test for independence in this setting.

b. Compute the expected counts assuming that H0is true.

c. Calculate the chi-square test statistic, df, and P-value.

d. What conclusion would you draw?

Last python Refer to Exercises 28 and 30.

a. Verify that the conditions for inference are met.

b. Use Table C to find the P-value. Then use your calculator鈥檚 蠂2 cdf command.

c. Interpret the P-value from the calculator.

d. What conclusion would you draw using 伪=0.10?
