The following data reflect the number of days people rented a car for a sample of people in each of three cities. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists between the population mean days corresponding to the three cities? Use the One-Way ANOVA test. STEP 1. State the Hypotheses, STEP 2. Decide on ?, STEP 3. Calculate Test Statistic, STEP 4. Find the Critical Value, STEP 5. Conclusion.
