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 significant level of 5%. Compact cars (643; 655; 702). Mid-size cars (469; 427; 525). Full-size cars (484; 456; 402). SST = 86049.556. SSE = 10254. TSS = 96303.556. What is the value of the F-statistic (rounded off 2 decimals)? A. 25.45 B. 25.59 C. 25.49 D. 25.18
