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?

Answer 1

Answer:

This is O.K to do, on the off chance that we are taking alpha level to 0.05 that implies that we are 95% sure that the drug is effective, and 5% isn't sure whether it is effective or not.

We have to report the public that the confidence level utilized for rejecting  the null hypothesis(H0) is 95%.

We own the expression as we have sufficient evidence in the support of the claim that new drug is effective at 0.05 level of significance.

In the event that we take the 99% confidence interval  than we won't have sufficient evidence  that the drug is effective.
