Question12.1 HW Part 3 of 5 Points: 0 of 1
The data from car crash tests for four different vehicle size categories (Small, Midsize, Large, and SUV) with measured amounts of left leg femur force (kN) results in the following Minitab display. Using a 0.05 significance level, test the claim that the four vehicle size categories have the same mean force on the femur of the left leg. Does size of the car appear to have an effect on the force on the left femur in crash tests?
Determine the null hypothesis. $$H_{0}: \mu_{1}=\mu_{2}=\mu_{3}=\mu_{4}$$
Determine the alternative hypothesis. $H_{1}$ : At least one of the means is different from the others Determine the test statistic. The test statistic is $\square$ (Round to two decimal places as needed.) Clear all Check answer
