Step 1: State the null and alternative hypothesis.
Step 2: Determine the level of significance
Using the .05 significance level, can we conclude that there is a difference in monthly rent at the other locations?
Step 3: Determine the test statistic: the test statistic is the F distribution
Step 4: Formulate the decision rule: Decision rule is to reject Ho if the calculated F is greater than the critical value of 3.89. Critical Value = 3.89 (Based off a numerator df of 2, and a denominator df of 12).
Step 5: Select the sample and perform the calculations
Step 6: Make a decision: We fail to reject the null hypothesis because the calculated F is less than the critical value of 3.89.
