Depakote is a medication whose purpose is to reduce the pain associated with migraine headaches. in clinical trials of Depakopte, 2% of the patients in the study experienced weight gain as a side effect. researchers claim that more than 2% of the patients experience weight gain. in a random sample of 30 Depakote users, 4 of them experience weight gain as a side effect. using a 1% significance level, test the researchers claim.  1. what is the population for the medication problem? a. all patients who take the depakote  b. all migraine sufferers c. the 30 depakote users d. all patients   2. a "success" in the medication problem would be defined as: a. being randomly chosen for the researchers study b. the patient not gaining weight c. taking depakote to treat migraines d. the patient gaining weight   3. the parameter being tested is: a. the 2% of the patients that gain weight b. the percentage of the patients that were chosen for the study c. the fraction of the patients in the sample…

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)?
