Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver's head during a crash test is equal for each types of car. Use a = .05. Use a post hoc test to determine which pairs of mean are significantly different. Explain in what way are they different. %3D Car: Compact Midsize Full-size 643 469 484 655 427 456 702 525 402 666.67 473.67 447.33 31.18 49.17 41.68 SS 1944.39 4835. 38 3474.45 Source SS df MS Between 86049.556 2 43024.778 25.1749 Within 10254.22 6. 1709.0367 Total 96303.776 8. 2. 3.
