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: Use Minitab or Excel to generate a summary table and the ANOVA table.
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.
