State the null and alternative hypotheses in the test for the effect of an interaction between row and column factors. Ho: There is no interaction between the subject's self-esteem and the target's self-esteem in determining self-esteem measures. H₁: There is an interaction between the subject's self-esteem and the target's self-esteem in determining self-esteem measures. What is the value of the test statistic for this test? F= (Round to two decimal places as needed.)

researcher notes that there seems to be a difference in the prevalence of high cholesterol among individuals who smoke and consume diets high in processed food and the prevalence of high cholesterol among individuals who do not smoke and do not consume diets high in processed foods. Use the appropriate hypothesis to test for independence of two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study's results. Then interpret your response. A. The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can accept H0 at the 5% level and reject H1, which states that smoking status and the incidence of high cholesterol are not independent of one another B. The chi square value of 37.724 is higher than the chi square value of 3.84, therefore we can reject H0 at the 5% level in favor of H1, which states that smoking status and the incidence of high cholesterol are not independent of one…
Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .05 significance level. The null and alternative hypothesis would be: Ho: HM = HF H,:PM = PF Ho: HM = PF Ho:HM = Pr Ho:PM = Pr Ho:PM PF H1: HM PF H1:HM > HF H1:HM # HF H1:PM + PF H1:PM < Pf The test is: right-tailed two-tailed left-tailed Based on a sample of 40 men, 40% owned cats Based on a sample of 40 women, 65% owned cats The test statistic is: (to 2 decimals) The p-value is: (to 4 decimals) Based on this we: O Reject the null hypothesis OFail to reject the null hypothesis Check Answer
Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 217 women, r1 = 52 responded yes. Another random sample of n2 = 175 men showed that r2 = 48 responded yes. Does this information indicate a difference (either way) between the population proportion of women and the population proportion of men who favor spending more federal tax dollars on the arts? Use ? = 0.05. (a) What is the level of significance? (b) What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.)(c) Find (or estimate) the P-value. (Round your answer to four decimal places.)

Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher studying psychological well-being between children from single-parent vs. two-parent families recruits 20 children from two-parent families and 20 children from single-parent families and measures their psychological adjustment.
Q: Using the data (provided below this question) test the hypotheses that the mean difference in writing and reading scores is zero and that the mean difference in math and science scores is zero. Use the paired-sample procedure. Use a 5% significance level if the problem doesn’t give an alpha. Note: Please only provide the t stat, p(T<=t) value and critical value. No need to explain the steps.

Mt. Dew is thinking about coming out with a new flavor. They are using a sample of 40 people who are tsting the new falvor. The people in the study were then given a questionnaire which evaluated how enjoyable to flavor was. The competing flavor has been studies extensively an population average value of 10.8. Write an appropiate null and alternative hypothesis ir order to test if there is a significant difference between the two drinks The ratings for the new Mt. Dew has an average of 14.4 and a sample standard deviation of 3.50. Calculate the test statistic for this hypothesis test. Calculate the p-value for this test statistic.

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
