A car manufacturer makes three models of cars (Model 1,Model 2 and Model 3).As part of their safety protocols,they are required to put their cars through three different kinds of accidents (head-on,slant and rear-end)and measure the $ amount of damage caused to the vehicles.The purpose of this type of test is to see if there are differences in average $ amount of damage across car models and/or different types of accidents. To test whether there are differences, they put each model of car through each type of accident a single time and record the $ amount of damage caused (see data below).

Head-on Slant Rear-end Model 1 $ 1,400 1,700 S 2,280 Model 2 S 1,740 1,850 S 2,480 Model 3 S 1,450 1,750 $ 1,900 Quantitative Question 4a What type of ANOVA test should they run with their data? O One factor ANOVA O Two factor ANOVA without replication O Two factor ANOVA with replication
