- The manager of a resort hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. (a) Which form of the hypotheses should be used to test the manager's claim? Explain. Ho: u 2 600 HaiH 600 Но: и 3D 600 Ha: u + 600 The hypotheses Ho: µ 2 600 and H: µ 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is less than or equal to 600 and find evidence to support u > 600. The hypotheses Ho: u = 600 and H: µ + 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is equal to 600 and find evidence to support u + 600.
