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 expected count of females who respond 鈥淎lmost certain鈥�?

a.487.7

b.525

c. 965

d.1038.8

e.1174

Short Answer

Expert verified

Option (d) Expected count of females who respond 鈥渁lmost certain鈥� is 1038.8.

Step by step solution

01

Given information

We have to identify the expected count of females who respond 鈥渁lmost certain鈥�.

02

Simplification

Given information two way tables is:

Opinion about marriage female male Total
Almost no chance 119 103 222
Some chance but probably not 150171321
A 50鈭�50 chance 447512959
A good chance 7357101445
Almost certain1174 7561930
Total 2625 2252 4877

For the given data expected count is 1038.8.

Thus, Option (d) is correct.

Most popular questions from this chapter

Do students who read more books for pleasure tend to earn higher grades in English? The boxplots show data from a simple random sample of 79 students at a large high school. Students were classified as light readers if they read fewer than 3 books for pleasure per year. Otherwise, they were classified as heavy readers. Each student鈥檚 average English grade for the previous two

marking periods was converted to a GPA scale, where A=4.0, A鈭�=3.7, B+=3.3

Reading and grades (3.2) The scatterplot shows the number of books read and the English grade for all 79 students in the study. The least-squares regression line y^=3.42+0.024x has been added to the graph.

a. Interpret the slope and y intercept.

b. The student who reported reading 17 books for pleasure had an English GPA of 2.85. Calculate and interpret this student鈥檚 residual.

c. For this linear model, r2=0.083 Interpret this value.

Inference recap (8.1to 11.2) In each of the following settings, state which inference procedure from Chapter 8,9,10,or11you would use. Be specific. For example, you might answer, 鈥淭wo-sample z test for the difference between two proportions.鈥� You do not have to carry out any procedures.

a. What is the average voter turnout during an election? A random sample of 38cities was asked to report the percent of registered voters who voted in the most recent election.

b. Are blondes more likely to have a boyfriend than the rest of the single world? Independent random samples of 300 blondes and 300 nonblondes were asked whether they have a boyfriend.

Where do young adults live? A survey by the National Institutes of Health asked a random sample of young adults (aged 19to 25years), 鈥淲here do you live now? That is, where do you stay most often?鈥� Here is the full two-way table (omitting a few who refused to answer and one who reported being homeless):

a. Should we use a chi-square test for homogeneity or a chi-square test for independence in this setting? Justify your answer.

b. State appropriate hypotheses for performing the type of test you chose in part (a). Here is Minitab output from a chi-square test.

c. Check that the conditions for carrying out the test are met.

d. Interpret the P-value. What conclusion would you draw?

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).

P-values For each of the following, find the P-value using Table C Then

calculate a more precise value using technology.

a. 蠂2=19.03,df=11

b. 蠂2=19.03,df=3
