A clinical trial is conducted comparing a new pain reliever for arthritis to a placebo. Participants are randomly assigned to receive the new treatment or a placebo and the outcome is pain relief within 30 minutes. The data are shown here.

Pain Relief No Pain Relief
New Medication 45 75
Placebo 20 100

Is there a significant difference in the proportions of

patients reporting pain relief?

Run the test at a 5% level of significance.

H0: p1= p2(equivalent to RD = 0, RR=1 or OR=1)

Can they reject the H0?

Group of answer choices

Yes, Reject H0, there is a statistically significant difference in the proportions of patients reporting pain relief in the new medication and placebo groups

No, Fail to Reject H0, there is no statistically significant difference in the proportions of patients reporting pain relief between the new medication and placebo groups

A study was performed comparing the efficacy of a new pain reliever, Galproxidone, to several pain relievers commonly prescribed after orthopedic surgury. Patients were asked to rate their pain after taking each medication. The data is listed below. Perform an ANOVA to determine the relative efficacy of Galproxidone on pain relief compared to the other pain relievers. If differences exist, perform a Bonferoni post-hoc test to determine which pain relievers are different from Galproxidone. Interpret the final results in terms...

A sample of 800 arthritis patients participate in a test of a new pain reliever. 624 of the participants rate their pain as ‘substantially reduced’. Give a 95% lower bound confidence interval for the proportion of arthritis patients whose pain would be substantially reduced when taking the new pain reliever. Interpret your result.
