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. TSS = 96303.556. State the appropriate hypotheses.  A. H0: μ1 = μ2 = μ3 vs H1: At least 2 of the means differ  B. Ho: μ1 ≠ μ2 ≠μ3 vs H1: μ1 = μ2 = μ3  C. Ho: At least 2 of the means differ vs H1: μ1 = μ2 = μ3  D. H1: μ1 = μ2 = μ3 vs Ho: At least 2 of the means differ
