Coverage-x-test/ t-test and NOVA

B. 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 = 5%. Compact cars Midsize cars 643 469 655 427 702 525 4. Formulate the null (Ho) hypothesis 5. What is the resulting degrees of freedom (df)? Solution: 6. What is the True Value (TV)? 7. What is the resulting computed value (CV)? Given: Solution: Full-size cars 484 456 402
