The study population consisted of HIV-infected women in sub-Saharan Africa who had been the single dose of Nevarpine (a treatment for HIV) while giving birth, to prevent transmission of HIV to the infant. The study was a randomized comparison of continued treatment of a woman aber successful childbirth) with Nevaripine vs. Lapinvi, a second drag med to treat HIV. There were 240 women who participated in the study, 120 were randomized to each of the two treatments. Twentyfour weeks after starting the study treatment, each won was tested to determine if the HIV infectie was becoming worse (ance called virologie fre). Twenty-six of the 120 women treated wi Nevaisine experienced virologicfilure, while 10 of the 120 women treated with the other drug experienced virologer future. A two way tahle presenting the results of this study is given below Virologie Failure Yes No Total Nevarii 26 94 130 Treatment Lopi 10 110 130 Total 36 204 (1) Suate appropriatelypothes to test for section of tatment and image blue (2) Complete the hypothesistent with the Chi-test and state an appropriate conclusion. Do the test musly, calculating all of the expected values, the Chi square tutti, and he to find the value. Use the significance level for the hypothesi test
Part 5. An industrial medical officer of a large factory was toimmune the company's employees against influenza rive vaccines of various types (1, 11, 1IIIV. and V) are available, but nobody knows which is preferable. From the work force, 675 employees agree to be immunited with one of the vaccines in the first week of December. In the first week of the following March he examines the records he has been keeping to see how many employees pot influence and how many did not The data for this inmination trial are listed in the Witched file, "Vaccine civ Create a crostation table for this trial (1) State appropriate hypotheses to test for whether the cene types are independent of influens rates Font (2) Calculate and report the totales (at percent) for each of the sacchetypes c) Confort the Chi Sure hypothesis and the appropriate conclusion Report the test nature, praw, and conclusion (use the 10% sparificance level) 6 Sappose you conducted a drug trial on a prop of animals and you hypothesized that the animals receiving the drug would show increased heartes compared to those that did not receive ther.
