Trying to encourage people to stop driving to campus, the university claims that on average it takes people 30 minutes to ﬁnd a parking space on campus. I don’t think it takes so long to ﬁnd a spot. In fact, I have a sample of the last ﬁve times I drove to campus, and I calculated the sample mean = 25. Assuming that the time it takes to ﬁnd a parking spot is normal, and that σ = 6 minutes, find the lowest level of significance at which the null hypothesis that it takes 30 minutes to find a parking space on campus can be rejected against the alternative that it takes less time. thanks in advance.
