Subjects with pre-existing cardiovascular symptoms who were receiving subitramine, an appetite suppressant, were foundto be at increased risk of cardiovascular events while taking the drug. The study included 9719 overweight or obesesubjects with preexisting cardiovascular disease and/ or type 2 diabetes. The subjects were randomly assigned tosubitramine (4787 subjects) or a placebo (4932 subjects) in a double-blind fashion. The primary outcome measured was theoccurrence of any of the following events: nonfatal myocardial infarction or stroke, resuscitation after cardiac arrest, orcardiovascular death. The primary outcome was observed in 557 subjects in the subitramine group and 505 subjects in theplacebo group.Do the data give good reason to think that there is a difference between the proportions of treatment and placebo subjectswho experienced the primary outcome?(a) State hypotheses, find the test statistic and use either software or Table A for the P-value.

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?

Individual actions can play a large role in the overall health of our planet. A researcher interested in evaluating environment friendly behaviors evaluated how often people recycle (per month) based on whether they have an overall optimistic or an overall pessimistic attitude toward eco-friendly behaviors. The results from this hypothetical study are given in the table. Test whether or not recycling behaviors differed between groups using a .05 level of significance. State the value of the test statistics and the decision to retain or reject the null hypothesis. Compute effect size using eta- squared (n^2).

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
Professor Chase from the University of Kansas has been working on a new cholesterol medication that is being called CholestoCleaner. The university is now conducting studies to determine if there is a possible side effect of sore joints. Placebo (Population Rate) To help determine the usual rate of sore joints, the research team gave a placebo (sugar pill) to 2017 subjects. Of those 2017 subjects, 4 of them developed sore joints. CholestoCleaner Trial The CholestoCleaner drug was given to 2622 subjects. Of those 2622 subjects, 19 of them developed sore joints. Preliminary Math If we consider the general population of people that don't use CholestoCleaner, what is the probability that they will develop sore joints? (Enter your answer as a fraction.) If you had a sample size of 2622 that did NOT use CholestoCleaner, how many would expect to develop sore joints? When 2622 subjects DID use the drug, there were 19 subjects that developed sore joints. Does it seem as though sore joints…

Adverse reactions of a drug used to help patients continue their abstinence from the use of alcohol have been studied in clinical trials, and the accompanying table summarizes results for digestive system effects among patients from different treatment groups. Use a 0.05 significance level to test the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group. Does the drug treatment appear to have an effect on the digestive system? Click the icon to view the data on adverse reactions from treatments. Determine the null and alternative hypotheses. OA. Ho: Drug treatment and adverse effects are not independent. H₁: Drug treatment and adverse effects are independent. OB. Ho: The drug treatment results in adverse effects on the digestive system.
