Exercise 2: Trying to encourage people to stop driving to campus, the university claims that on average it takes people more than (30+m) minutes to find a parking space on campus. Randomly selected 40 drivers and found that the mean time for parking is (24+m) minutes. Assuming that the time it takes to find a parking spot is normal, and that population standard deviation is known to be 6 minutes, and then perform a hypothesis test with level 10% significance to see if the claim is correct. Assign null and alternate hypotheses using
