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. the test statistic to use is a. the number of successes in the sample, 4 b. the total number of trials obtained by the reasercher, 30 c. the fraction of patients that gained weight, 2% d. the percentage of patients that gained weight, p hat = 4/30 if the 2% claim from the researchers is true for the population, the chance of exactly 3 experienced weight gain as a side effect is: a. 0.9971 b. 0.0188 c. 0 d. 0.0029 the p-value in the medication case is a. none of these b. 0.0188 c. 0.0029 d. 0.9971 the most extreme evidence for the alternative hypothesis in the medication case is: a. every patient experienced weight gain as a side effect b. exactly 2% of the patients in the sample experience weight gain as a side effect c. no patient experinced weight gain as a side effect d. the 30 patients in the sample are shown to have the same probability of being chosen for the study as any other 30 patients taking depakote the proper decision and conclusion that should be made by the researchers concerning the side effects for the medication population is: a. do not reject H0, we have sufficient evidence to conclue that more than 2% of the patients that take depakote exerience weight gain as a side effect b. reject H0, we have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect c. reject H0, we do not have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect d. do not reject H0, we do not have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect
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.
the test statistic to use is
a. the number of successes in the sample, 4
b. the total number of trials obtained by the reasercher, 30
c. the fraction of patients that gained weight, 2%
d. the percentage of patients that gained weight, p hat = 4/30
if the 2% claim from the researchers is true for the population, the chance of exactly 3 experienced weight gain as a side effect is:
a. 0.9971
b. 0.0188
c. 0
d. 0.0029
the p-value in the medication case is
a. none of these
b. 0.0188
c. 0.0029
d. 0.9971
the most extreme evidence for the alternative hypothesis in the medication case is:
a. every patient experienced weight gain as a side effect
b. exactly 2% of the patients in the sample experience weight gain as a side effect
c. no patient experinced weight gain as a side effect
d. the 30 patients in the sample are shown to have the same probability of being chosen for the study as any other 30 patients taking depakote
the proper decision and conclusion that should be made by the researchers concerning the side effects for the medication population is:
a. do not reject H0, we have sufficient evidence to conclue that more than 2% of the patients that take depakote exerience weight gain as a side effect
b. reject H0, we have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect
c. reject H0, we do not have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect
d. do not reject H0, we do not have sufficient evidence to conclude that more than 2% of the patients that take depakote experience weight gain as a side effect
