Researchers are concerned with patient's ability to tolerate the newtreatment. Thus, they decided to assess their quality of life both before and afterreceiving the new chemotherapy treatment. Quality of life (QOL) is rated from 1 to5 where 1=Poor, 2= Fair, 3=Good, 4= Very Good, 5 = Excellent. Consider thefollowing result of the Paired Wilcoxon Signed Rank Test.%3Ddata:QOL before and QOL afterV = 8, p-value = 0.04371alternative hypothesis: true location shift is not equal to 0

Given information: V = 8 P-value = 0.04371

Use the attached image to answer the question: Use the data above to construct a bivariate table and explore if there is an association between one’s education and attitudes toward cohabitation. Is there an association? Describe the pattern of association. Assuming that this is a random sample, test a hypothesis (use α = 0.01) that there is an association between one’s education and attitudes toward cohabitation in the population. Show all your work (state the hypotheses, find the critical value, compute the test statistics, state a conclusion) and write one sentence summarizing the results. (Extra-credit: find the p-value). Is this association weak, moderate or strong? Compute and interpret the appropriate statistic.
Shark scientists are interested in whether the magnitude of hammer-head shark migration is related to the temperature of the local coastal area. They divided the coast into 8 parts based on topography, and then they measured each part's temperature level during the shark migration and the number of sharks that migrated. Which type of statistical test should they use to analyze their data? O Independent samples t test Single Sample t-test Paired samples t test Pearson's r correlation O Z test One-way ANOVA Simple linear regression
