need full and complete answer of this question

2. The quality control team wish to investigate the rollover rates between two types of vehicles, A and B. Among 120 tests on each type, 39 of the A's and 33 of the B's failed the test. Can we conclude that vehicle A has a higher rollover rate than vehicle B? Assume α = 0.05. a. Write the appropriate hypothesis. b. Use P-value approach for hypothesis testing c. Use z-test for hypothesis testing d. Use confidence interval for hypothesis testing. e. Clearly write your conclusion f. If the true rollover rates are pa' = 0.4 and pB-0.25, what is the type II error? g. If the true rollover rates are pA 0.4 and p 0.25, what is the minimum sample size needed to detect that difference with 99% probability?
