Suppose that a train conductor claims that the variance of the time required to go from Point A to Point B is 133 minutes. 60 train rides between Point A and Point B last month were reviewed at random. For those 60 rides, the variance of the times required to go from Point A to Point B was 150 minutes. At a significance level of .05, is there enough information to reject the train conductorâ€™s claim?
The Student Helpline provides academic assistance to students so that they can complete their university assignments and projects on time. Our business does NOT deal with ghostwriting services as we are aware of this being one of the academic misconducts. But we do help students by connecting them to online subject experts within an affordable price range.
