## Test whether the mean pressure applied to the driver’s head during a crash test is equal for each type of car.

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).

 Compact Cars Midsize Cars Full size Cars 643 469 484 655 427 456 702 525 402

b) Using the hypothetical data provided above, test whether the mean pressure applied to the driver’s head during a crash test is equal for each type of car. Use α =5%.
