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 car types. Using the data provided below
Pressure | Car Type |
643 | Compact |
655 | Compact |
702 | Compact |
469 | MidSize |
427 | MidSize |
525 | MidSize |
484 | FullSize |
456 | FullSize |
402 | FullSize |
Test, using Mood’s Median Test, whether the median pressure applied to the driver’s head during a crash test is equal for each types of car. Use α = 5%. Show the appropriate output from Minitab to support your claim and state the significance level you used.
