In two separate clinical trials of new drugs, the null hypothesis of no efficacy for drug A is rejected at the significance level p=0.0001, and the null hypothesis of no efficacy for drug B is rejected at the significance level p=0.01, then Drug A is much more effective than Drug B.
Statment is fully correct
Explanation: Drug A has p=0.0001 means it has 99.99% confidence to prove its effectivness wheras drug B has onley 99% confidence.In simple words A has more evidence than B to prove its effectivness.
Rational:If we have evidence for 99.99% confidence it says we have automatically evidence for the confidence lesser than 99.99% (such as 90%,99%).But if we are sure for 99% onley this never means it also having surity for greater than 99% (such as 99.99% etc)
