A simple random sample of 148 Introduction to Statistics students were asked whether or not they thought they would ever use statistics again in their lives. The following table gives the results: Would use | Would not use Men | 47 | 21 Women | 64 | 16 Question 1 To compute the chi-square test statistic, expected frequencies were calculated. What is the expected frequency for the men who answer "would use"? 51 44 47 64 56 Question 2 Have many degrees of freedom chi-square statistics have? 1 2 3 4 The chi-square statistic to test the null hypothesis that sex and anticipated use are independent is 2.32. Can you conclude that there is an evidence of dependence between sex and anticipated use at significance level 0.05?

Step 1
We can do this by adding the number of men and women who would use and would not use statistics: Total students = 47 (men would use) + 21 (men would not use) + 64 (women would use) + 16 (women would not use) = 148 Show more…

Perform the indicated chi-square independence test by doing the following. (a) Identify the claim and state $H_{0}$ and $H_{a}$ (b) Determine the degrees of freedom, find the critical value, and identify the rejection region. (c) Find the chi-square test statistic. If convenient, use technology. (d) Decide whether to reject or fail to reject the null hypothesis. (e) Interpret the decision in the context of the original claim. You work for a college's continuing education department and want to determine whether the reasons given by workers for continuing their education are related to job type. In your study, you randomly collect the data shown in the contingency table. At $\alpha=0.01,$ can you conclude that the reason and the type of worker are dependent? (FIGURE CAN'T COPY)

If convenient, use technology. (d) Decide whether to reject or fail to reject the null hypothesis. (e) Interpret the decision in the context of the original claim. Achievement and School Location The contingency table shows the results of a random sample of students by the location of school and the number of those students achieving basic skill levels in three subjects. At $\alpha=0.01,$ test the hypothesis that the variables are independent. (FIGURE CAN'T COPY)
