The manager of a resort hotel stated that the mean guest bill for a weekend is $1,400 or less. A member of the hotel's accounting staff noticed that he 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) Consider the following hypotheses. Ho:μ ≥ 1,400 Ha: < 1,400 Ho: ≤ 1,400 Ha: > 1,400 Ho: μ = 1,400 Ha: 1,400 Which form of the hypotheses should be used to test the manager's claim? Explain.

The manager of a resort hotel stated that the mean guest bill for a weekend is $1,400 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) Consider the following hypotheses. Ho: μ ≥ 1,400 Ha: μ< 1,400 Ho:μ ≤ 1,400 H₂:μ > 1,400 Which form of the hypotheses should be used to test the manager's claim? Explain. The hypotheses Ho: μ ≥ 1,400 and H₂:μ < 1,400 should be used because the accountant wants to test the manager's claim that the mean guest bill μ is greater than or equal to 1,400 and find evidence to support μ< 1,400. 0 0 0 0 0 Ηγ: με = 1,400 Ha: μ # 1,400 0 0 0 0 0 The hypotheses Ho: μ≤ 1,400 and H₂: > 1,400 should be used because the accountant wants to test the manager's claim that the mean guest bill is less than or equal to 1,400 and find evidence to support μ > 1,400. (b) What conclusion is appropriate when Ho cannot be rejected? The hypotheses Ho: μ = 1,400 and H₂: μ ‡ 1,400 should be used because the accountant wants to test the manager's claim that the mean guest bill μ is equal to 1,400 and find evidence to support μ 1,400. We are not able to conclude that the manager's claim is wrong. We can conclude that μ ≥ 1,400. We are able to conclude that the manager's claim is wrong. We can conclude that μ = 1,400. We are not able to conclude that the manager's claim is wrong. We cannot conclude that µ ‡ 1,400. We are not able to conclude that the manager's claim is wrong. We cannot conclude that μ > 1,400. We are able to conclude that the manager's claim is wrong. We can conclude that μ ≤ 1,400. (c) What conclusion is appropriate when Ho can be rejected? We are able to conclude that the manager's claim is wrong. We can conclude that μ > 1,400. We are able to conclude that the manager's claim is wrong. We can conclude that μ< 1,400. We are not able to conclude that the manager's claim is wrong. We can conclude that µ< 1,400. We are not able to conclude that the manager's claim is wrong. We can conclude that µ > 1,400. We are able to conclude that the manager's claim is wrong. We can conclude that μ ‡ 1,400.
