A study was conducted to compare automobile gasoline mileage for three brands of gasoline, A, B, and C. Four automobiles, all of the same make and model, were used in the experiment, and each gasoline brand was tested in each automobile. Using each brand in the same automobile has the effect of eliminating (blocking out) automobile-to-automobile variability. The data {in miles per gallon} are as follows: A B C 18.2 18.5 19.3 19.1 18.7 18.0 Use Minitab or Excel to generate a summary table and the ANOVA table. Round your answers to two decimal places. Do the data provide sufficient evidence to indicate a difference in mean mileage per gallon for the three brands of gasoline? F = p-value = There sufficient evidence to indicate a difference in mean mileage per gallon for the three brands of gasoline. Is there evidence of a difference in mean mileage for the four automobiles? F = p-value = There sufficient evidence to indicate a difference in mean mileage per gallon for the four automobiles
