Suppose the Land Transportation and Franchising Regulatory Board (LTFRB) wants to examine the safety of Public Utility Vehicles (PUVS)- Jeepneys, Van and Buses. It collects a sample of three for each of the PUVS for analysis. 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 type of PUVS. Use a =5%. JEEPNEY VAN BUS 643 469 484 655 427 456 702 525 402 Using the data in the previous example, at a = 0.05 level of significance, test the claim that the two populations have equal means. STEP 1: State the hypotheses Ho: 41 = 42 Ha: H1 * 42 STEP 2: Level of Significance a=0.05 STEP 3: Determine the critical value Since a=0.05 and the test is right-tailed, dfNumerator %3D dfpenominator = The critical value is
