The Data From Car Crash Tests For Four Different Vehicle Size Categories Small Midsize Large And Suv With Measured 1 (50.01 KiB) Viewed 32 times

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? Analysis of Variance Source DF Adj SS Size 3 0.6225 52 19.2712 55 19.8937 Error Total Adj MS 0.2075 0.3706 Determine the null hypothesis. Ho: Determine the alternative hypothesis. H₁: F-Value 0.56 P-Value 0.644 Determine the test statistic. The test statistic is. (Round to two decimal places as needed.) Determine the P-value. The P-value is (Round to three decimal places as needed.) Does size of the car appear to have an effect on the force on the left femur in crash tests? Ho. There ▼sufficient evidence at a 0.05 significance level to warrant rejection of the claim that the four vehicle size categories have the same mean force on the left femur crash tests.
