A new drug, Comsense, is used to treat addiction to Velveeta. In a clinical trial among subjects treated with Comsense, 52 developed headaches and 175 did not develop headaches. Among other subjects given placebos, 5 developed headaches and 40 did not develop headaches. Use a 0.05 significance level to test for a difference between the rates of headaches for those treated with Comsense and those given a placebo.

A doctor is concerned that nausea may be a side effect of Tamiflu, but is not certain because nausea is common for people who have the flu. She researched some past studies, and found that about 30% of people who get the flu and do not use Tamilflu experience nausea. She then collected data on 2422 patients who were taking Tamiflu, and found that 666 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is 30%. What type of test will be used in this problem? What evidence justifies the use of this test?

An RCT was designed to test the effectiveness of naltrexone, an opiate receptor antagonist, as a treatment for alcohol dependence. Subjects with chronic severe alcohol dependence were randomly assigned to either 3 months of naltrexone treatment or 3 months of placebo treatment. The number of drinks per drinking day was compared between the two groups. Let μ1= population mean number of drinks per drinking day for those on Naltrexone and μ2= population mean number of drinks per drinking day for those on placebo. The data from the study are summarized in the table below. Naltrexone(n1 = 196) Placebo (n2=195) Mean Number of drinks perdrinking day Xbar1=10.5 Xbar2=9.3 Standard Deviation of Numberof drinks per drinking day S1= 80 S2= 7.0 The investigators want to test whether there is a significant difference between the two groups using a 5% significance level. 1. What is the most appropriate test to address the investigators’ research question? a. Pearson’s Chi-Squared…
