Steps in Hypothesis Testing: Videos & Practice Problems

A new medication is tested to determine if it lowers blood pressure more effectively than a placebo. The alternative hypothesis is that the medication leads to a greater reduction in blood pressure, meaning the mean reduction is greater than zero. After conducting the experiment, the following $p$-values are possible outcomes: $0.850$, $0.400$, $0.070$, $0.020$, $0.005$, and $0.950$. If you want to demonstrate the medication's effectiveness, which $p$-value would you most want to obtain?
