Question

A Clinical trial is conducted comparing a new pain reliever for arthritis to a placebo Participants are randomly assigned to recede the new treatment or a placebo and the outcome is pain relief within 30 minutes The data are shown below The question wanted to know if there was a significant difference in the proportions of patients reporting pain relief and you ran the appropriate test at a 5% level of significance if your decision rule was "Reject HD if z 1 96" and your computed test statistic is Z=3.35. what is your conclusion? Do not reject H_0 because 3 35 greaterthanorequalto 1.96 Reject Ho because 3.35 greaterthanorequalto 1 96 We have statistically significant evidence at alpha=0.05 to show that there is a difference m proportions of patients reporting pain relief. We do not have statistically significant evidence at alpha=0.05 to show that there is a difference in proportions of patients reporting pain relief Both a & d should be included m the conclusion Both b & c should be included in the conclusion

Explanation / Answer

Here' my take on the question:

The null hypothesis will be that there is no difference and alternate hypothesis is that there is actually difference.

Hence, since 3,35>=1.96 we reject null hypothesis, and conclude the statement is part C) We have statistically significant evidence...

So, B and C are the answer to this question
