Suppose a hypothesis test is performed relating to the effectiveness of a new dr

Question

Suppose a hypothesis test is performed relating to the effectiveness of a new drug for cancer. You make a conclusion based on a .01 alpha level that there is not enough evidence to say the drug is effective. You realize that if you just change the alpha level to .05 you can change your conclusion to say that there is enough evidence to support the drug's effectiveness.

Discuss your feeling about the scenario above. Are there ethical considerations? Is this ok to do? What do you need to report to the public? What kind of statement do you make to the "people" so they will understand your conclusion? What other comments/ideas do you have? What does this mean for this drug? Is it effective or is it not?

Explanation / Answer

Solution:-

This is O.K to do, if we are taking alpha level to .05 that means that we are 95% sure that the drug is effective, and 5% is not sure whether it is effective or not.

We need to report the public that the confidence level used for rejecting the null hypothesis is 95%.

We make the statement as we have suffcient evidence in the favor of the claim that new drug is effective at 0.05 significance level.

If we take the 99% confidence interval than we will not have suffcient evidence that drug is effective.
