A researcher conducted an Independence test by using data consisting of 2 categorical variables: Zip code and Diet. Her data can be organized into a 3 by 4 contingency table. If she found the test statistic χ2=χ2=10.7: What is the degree of freedom of the χ2χ2 statistic? What is the P-value of the Independence test? (Round to 3 decimals) Given the significance level of 0.1, what can she conclude from the test? Zip code and diet are independent of one another. Zip code and diet are dependent on one another.

If the null hypothesis in a t-test for two samples is not rejected, what conclusion can be drawn about the two means of the categorical variable? Assume you collected larger samples of individuals to test your null hypothesis in question #1. Specifically, the sample sizes increased to 200 subjects in each group. Do your results and conclusions change from the test of the smaller sample sizes? (You must show your work).
A social psychologist was interested in finding out whether the effect of leadership style on the productivity of workers at an assembly plant for fax machines. A team of 15 workers were supervised by democratic leaders, while a team 15 workers were supervised by autocratic leaders. The average number of fax machines assembled in an hour by each team was recorded. Conduct the 7 steps of hypothesis testing, including a t test to see if there was a significant difference between the two styles of leaders.
College administrators at the same institution are further concerned about the differences in binge drinking behaviors among men and women on campus. Suppose of the 268 participants surveyed about their drinking habits that reported binge drinking behaviors, 94 were female. Is there statistically significant evidence at the alpha level of 0.05 that males partake in binge drinking behaviors more so than females involved in Greek life organizations? Write out your null and alternative hypotheses and interpret your results. A. Hypotheses: H0: p=0.50 and Ha: p<0.50 B. Test Statistic: (Normal approximation to the binomial is used) ��^ = 0.03054 zstat= -4.88678 C. P-value: P < 0.0002 D. Significance level: Are the results significant? Group of answer choices Yes, the evidence against H0 is not sufficient to warrant its rejection. Yes, the evidence against H0 is sufficient to warrant its rejection. No, the evidence against H0 is not sufficient to…
A recent study looked at the relationship between condom use and the spread of AIDS, by following heterosexual couples in which one partner was infected with HIV. The couples were classified by their condom use. Of the 98 couples who always used condoms, 4 partners became infected with HIV. Of the 67 couples who did not always use condoms, 11 partners became infected. Test whether the proportions of partners who became infected with HIV are different for each group, using a 5% level of significance. Give each of the following: 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.

According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.36. Suppose a random sample of 110 traffic fatalities in a certain region results in 49 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=0.05 level of significance?
A sports fan would like to determine if "home-field advantage” exists in soccer. He looks back through a random sample of 80 professional soccer matches and determines that the team playing at home won 51 of those matches. Does this sample provide strong evidence that the home team wins more than half of all professional soccer matches, at the = 0.01 significance level? A. The test statistic is z = 2.45 and the P-value = 0.007; thus, we can conclude that home teams win more than half of their matches because 0.007 < 0.01. B. The test statistic is z = 2.45 and the P-value = 0.014; thus, we cannot conclude that home teams win more than half of their matches because 0.014 > 0.01. C. The test statistic is z = 2.45 and the P-value = 0.993; thus, we cannot conclude that home teams win more than half of their matches because 0.993 > 0.01. D. The test statistic is z = 2.45 and the P-value = 0.007; thus, we cannot conclude that home teams win more than half of their matches because…
