We use the hypothesis test to determine if there is strong evidence that this null hypothesis is incorrect. The next step of the hypothesis test is our alternative hypothesis, H
Hypothesis Testing – Examples and Case Studies. 23.1 How Hypothesis Tests Are Reported in the News. Determine the null hypothesis and the alternative hypothesis. Collect and summarize the data into a . test statistic. Use the test statistic to determine the p-value. The result is statistically significant if the .
