The number of cars passing eastbound through the intersection of Mill Avenue and University Avenue has been tabulated by a group of civil engineering students. They have obtained the following data: a) Does the assumption of a Poisson distribution seem appropriate as a probability model for this process? Use a = 0.05. b) Calculate the P-value for this test. (you can use Minitab to find the p-value)
