3. A university examines the variability in the math scores of students accepted to the business and engineering schools. The table below presents sample data from the most recent incoming class. Engineering Business Sample Standard Deviation 122.4 106.5 Sample Size 16 19 Perform a hypothesis test to determine whether the variation in math scores is different if a = 0.05. 4. The gas mileage of three different cars based on random samples are shown in the table below. Model 3 17.2 18 21.1 19.8 Model 11 Model 2 24.5 23.7 20.8 19.8 22.6 24 23.6 23.1 21 24.9 Perform a hypothesis test to determine whether there is a difference in gas mileage between the three car models at the a= 0.05 significance level.
