Discuss the five steps in hypothesis testing.
What will be an ideal response?
Step 1. State the null hypothesis and the research, or alternative hypothesis.
Step 2. Select an appropriate test statistic and obtain the sampling distribution for that statistic.
Step 3: Select a level of significance, termed our alpha level, and identify the critical region.
Step 4. Calculate the obtained test statistic using the data we obtained from our sample.
Step 5. Make a decision about the validity of the null hypothesis based on the results of our statistical test. We do this by comparing our critical value of z with the value we obtain from our statistical test or by seeing if our obtained statistic falls into our defined critical region.
