24 Hypothesis testing steps: Step 1: Determine the null and alternative hypotheses Step 2: Verify necessary data conditions, and if met, summarize the data into an appropriate test statistic. Step 3: Assuming the null hypothesis is true, find the p-value. Step 4: Decide whether or not the result is statistically significant based on the p-value. Step 5: Report the conclusion in the context of the problem.
