A case-control study of patients on antihypertensive drugs related an increased risk of myocardial infarction (MI) for patients using calcium channel blockers. In this study, cases were antihypertensive drug patients who had suffered a first fatal or nonfatal MI through 1993, and controls were antihypertensive drug patients, matched by demographic factors, who had suffered a MI. Among the comparisons reported were patients receiving calcium channel (CC) blockers (with and without diuretics) and patients receiving ß-blockers (with and without diuretics). Results of numbers of patient by drug/MI status combination are given in the following table. Antihypertensive OHO: p1p2 vs. Ha: p1 < p2 O HO: p1> p2 vs. Ha: p1=p2 Drug Does it appear that an increased risk of myocardial infarction (MI) is related to using calcium channel (CC) blockers? The case-control nature of this study requires we compare the proportion of CC blocker users among those had MI attack (p1) vs. the proportion of CC blocker users among those had no MI (p2). What is your hypothesis for this test? O HO: p1p2 vs. Ha: p1=p2 CC blocker B-blocker O HO: p1=p2 vs. Ha: p1 > p2 Occurrence of Yes (cases) 80 85 Myocardial Infarction No (controls) 230 395

Can you please explain where the critical value and rejection region came from? I attached the question as well. I just need an understanding of where the critical value and rejection came from, please break it down for me because I can't figure it out, thanks. I circled it in blue
I want to assess whether or not students produce more stress hormones (cortisol) after watching different types of movies. I collect saliva samples (to assess cortisol, stress) from students after they watch an action movie and then another (two days later) after they watch a horror movie. The amount of stress hormone in the saliva is measured as ng/mL.Test the hypothesis that saliva cortisol levels will be different between the two genres of movies at an alpha of 0.05. (Have action - horror be set for your differences).

Calculate the X² statistic then compare it with the critical value to determine if we will reject or fail to reject the null hypothesis that "There is no difference in the proportion of students that choose STEM, Social Sciences and Liberal Arts"
Define the critical region for a hypothesis test, and explain how the critical region is related to the alpha level.
We wish to test an effect of a drug that claimed to improves the patients with 80% of chance. The drug is given to 20 patients and we observed the number Y of people who improved. The hypothesis is Ho :p = 0.8 vs Hị : p< 0.8. Use the rejection region RR = {y< 12} and answer question a-e.
I did this question already, I would just like some confirmation if my answers are correct. my answers to this problem were: Reject H0 and The test statistic falls within the region.
If a treatment is expected to decrease scores in a population with µ= 30, then the alternative hypothesis is µ ≤ 30. True or false?

A study is planned to investigate risk factors for sudden cardiac death. A cohort of men and women between the ages of 35 and 70 is enrolled and followed for up to 20 years. As part of the study, participants provide data on demographic and behavioral characteristics; they also undergo testing for cardiac function and provide blood samples to assess lipid profiles and other biomarkers. A new measure of inflammation is hypothesized to be related to sudden cardiac death. Describe its strengths and weaknesses.
