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 that gained weight d. the proportion of all the patients that gained weight while using depakote medication 4. the correct null and alternative and hypotheses are: a. H0: p = 0.02, HA: p < 0.02 b. H0: mu = 0.02, HA: mu < 0.02 c. H0: p = 0.02, HA: p does not equal 0.02
