Car Crash Tests? The following table lists results from car crash tests. The listed values are measures of chest deceleration (in g) categorized by type (whether the car is foreign or domestic) and car size (small, midsize, large). Results from two-way analysis of variance are also displayed. Use the displayed results and use a 0.05 significance level. What do you conclude?
Solution 6BSC Step 1: From the given information the data is based on the car crash tests are characterized by type,( whether the car is foreign or domestic) and car (size, small,midsize and large). The Minitab output for the two-way analysis of car crash test is given as, Step 2: For interaction factor: The test statistic is F = 0.34 and the p-value is 0.717. Comparing the p-value with significance level 0.05. Here the p-value is larger than the significance level. So there is no sufficient evidence to conclude that is an interaction effect.
