A migraine is a particularly painful type of headache, which patients sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine pain, researchers conducted a randomized controlled study where 89 females diagnosed with migraine headaches were randomly assigned to one of two groups: treatment or control. 43 patients in the treatment group received acupuncture that is specifically designed to treat migraines. 46 patients in the control group received placebo acupuncture (needle insertion at nonacupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain free. Results are summarized in the contingency table below. Pain free? Yes No Total Treatment Group 10 33 43 Control Group 2 44 46 Total 12 77 89 a) Compute the row proportions.

Treatment of patients whose injuries might cause massive blood loss has involved giving them plasma transfusions after they had been admitted to the emergency room. Sperry et al. (2018) investigated whether earlier treatment by the first responder might be more effective. In a randomized control trial, patients with trauma either did or did not receive earlier plasma transfusion. Of the 220 patients who received early plasma treatment, 52 died while of the 261 who received standard care, 89 died. Does the earlier treatment of plasma transfusion seem to be more effective? Standard Treatment 89 Early Treatment Died 52 Survived 167 173 What analysis is appropriate to run? heteroscedastic t-test Opaired t-test odds ratio O chi-squared goodness of fit homoscedastic t-test
Migraine and Acupuncture: A migraine is a particularly painful type of headache, which patients sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine pain, researchers conducted a randomized controlled study where 154 patients diagnosed with migraine headaches were randomly assigned to one of two groups: treatment or control. 68 patients in the treatment group received acupuncture that is specifically designed to treat migraines. 86 patients in the control group received placebo acupuncture (needle insertion at non- acupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain free.

After the second dose, 61 of 545 of the subjects in the control group (group 2) experienced drowsiness as a side effect.

Whirling disease is a deadly disease that affects trout in Montana riversIn a follow-up to a 2006 study conducted by the Montana Department of FishWildlife and Parks (FWP)researchers sought to determine if the proportion of trout afflicted by whirling disease in the Gallatin river differs between rainbow trout and brown trout. To test this theory, researchers collected a representative sample of 527 rainbow trout and 459 brown trout. Of the 527 rainbow trout collected, 120 had developed whirling disease; of the 459 brown trout collected, 74 had developed whirling disease Calculate the relative risk of whirling disease for rainbow trout compared to brown trout in this sample.

A study was performed to test the effectiveness of aspirin in the treatment of strokes. There were 200 patients in the study. A random sample of 110 of these patients were placed in the “aspirin” group, and the remaining 90 in the “control” group. After six months of treatment, all the patients were evaluated and their condition recorded as either favorable or unfavorable. Of the 110 “aspirin” patients, 72 had favorable outcomes; of the 90 “control” patients, 53 had favorable outcomes. We want to test the null hypothesis that the percentage of favorable outcomes is the same between the two conditions.   Write down the box model for the null hypothesis as a sentence or picture of the box.               Under the null hypothesis, the difference in the sample percentages is expected to be ________%, and the standard error for the difference is ________%.        Calculate the appropriate two-sample z test statistic.             Calculate the p-value and express what it means in plain…
Subjects with pre‑existing cardiovascular symptoms who were receiving subitramine, an appetite suppressant, were found to be at increased risk of cardiovascular events while taking the drug. The study included 9645 overweight or obese subjects with preexisting cardiovascular disease and/ or type 22 diabetes. The subjects were randomly assigned to subitramine (4798 subjects) or a placebo (4847 subjects) in a double‑blind fashion. The primary outcome measured was the occurrence of any of the following events: nonfatal myocardial infarction or stroke, resuscitation after cardiac arrest, or cardiovascular death. The primary outcome was observed in 552 subjects in the subitramine group and 491 subjects in the placebo group. Do the data give good reason to think that there is a difference between the proportions of treatment and placebo subjects who experienced the primary outcome? (a) State hypotheses, find the test statistic and use either software or Table A for the ? Give both the test…
An epidemiologist found five cases of “big toe cancer” in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete’s foot, and history of ingrown toenails. The following data were gathered: Shoe size > 9 Pair Case Control 1 Yes No 2 No No 3 No Yes 4 Yes Yes 5 No Yes Compute the proper measure of association. Interpret your results. If you were to investigate a rare cancer in Lynchburg, where might you look for data? What would be necessary legally and ethically to be able to utilize this data set(s)?

In randomized, double-blind clinical trials of a new vaccine, toddlers were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 121 of 379 subjects in the experimental group (group 1) experienced nausea as a side effect. After the second dose, 150 of 595 of the subjects in the control group (group 2) experienced nausea as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced nausea as a side effect than subjects in group 2 at the α = 0.10 level of significance?
