Question
Three different models of automobiles (A, B, and C) were compared for gasoline consumption. For each model of car, ten cars were randomly selected and subjected to standard driving procedures. The average miles/gallon obtained for each model of car and sample standard deviations are shown below.| Car A | Car B | Car C | |
| Average Mile/Gallon | 42 | 49 | 44 |
| Sample Standard Deviation | 4 | 5 | 3 |
Use the above data and test to see if the mean gasoline consumption for all three models of cars is the same. Let a= 0.05. Show the complete ANOVA table.
