1. [-/1.5 Points] DETAILS MY NOTES PRACTICE ANOTHER The manager of a resort hotel stated that the mean guest bill for a weekend is $800 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: A = 800 Ha 800. The hypotheses Ho: = 800 and H: 800 should be used because the accountant wants to test the manager's claim that the mean guest bill is 800 and find evidence to support + 800. (b) What conclusion is appropriate when Ho cannot be rejected? Do not reject the manager's claim. Conclude there is not evidence to support that * 800. Do not reject the manager's claim. Conclude there is not evidence to support that 800. Reject the manager's claim. Conclude there is evidence to support that 800. Reject the manager's claim. Conclude there is evidence to support that = 800. Do not reject the manager's claim. Conclude there is not evidence to support that > 800. (c) What conclusion is appropriate when Ho can be rejected? Do not reject the manager's claim. Conclude there is not evidence to support that > 800. Reject the manager's claim. Conclude there is evidence to support that < 800. O Reject the manager's claim. Conclude there is evidence to support that > 800. Reject the manager's claim. Conclude there is evidence to support that 800. Do not reject the manager's claim. Conclude there is not evidence to support that < 800. 2. [-/1.5 Points] DETAILS MY NOTES PRACTICE ANOTHER A production line operation is designed to fill cartons with laundry detergent to a mean weight of 64 ounces. A sample of cartons is periodically selected and weighed to determine whether underfilling or overfilling is occurring. If the sample data lead to a conclusion of underfilling or overfilling, the production line will be shut down and adjusted to obtain proper filling. (a) Select the correct null and alternative hypotheses needed to determine whether to shut down and adjust the production line. Ho: 64 Ha: < 64 Hoi H = 64 Ha H > 64 Hoi u = 64 H: < 64 Ho: 64 H > 64 o Hon = 64 H: 64 (b) Select the appropriate conclusion and decision when Ho cannot be rejected. Conclude that there is not statistical evidence that the production line is not operating properly. Do not allow the production process to continue. Conclude that there is not statistical evidence that the production line is not operating properly. Allow the production process to continue. Conclude that there is statistical evidence that the production line is not operating properly. Allow the production process to continue. O Conclude that there is statistical evidence that the production line is not operating properly. Do not allow the production process to continue. (c) Select the appropriate conclusion and decision when Ho can be rejected. Conclude that there is statistical evidence that overfilling or underfilling exists. Do not shut down and adjust the production line. Conclude that there is statistical evidence that overfilling or underfilling exists. Shut down and adjust the production line. Conclude that there is not statistical evidence that overfilling or underfilling exists. Shut down and adjust the production line. Conclude that there is not statistical evidence that overfilling or underfilling exists. Do not shut down and adjust the production line. 3.
