Decide whether to reject the null hypothesis by comparing the p-value to α (i.e. reject the null hypothesis if p < α) Report your results, including effect sizes (as described in Effect Size ) Observation : Suppose we perform a statistical test of the null hypothesis with α = .05 and obtain a p-value of p = .04, thereby rejecting the null hypothesis.

Therefore, the null hypothesis is that the drug is safe. The alternate hypothesis — the one you want to replace the null hypothesis, is that the drug
