Question

5. (1 0 points) A hotel chain is interested in evaluating reservation processes. Guests can reserve a room by using either a telephone system or an online system that is accessed through the hotel's web site. Independent random samples of 80 guests who reserved a room by phone and 60 guests who reserved a room online were selected. Of those reserved by phone, 57 reported that they were satisfied with the reservation process. Of those who reserved online 50 reported that they were satisfied. Based on these data, is it reasonable to conclude that the proportion who are satisfied is greater for those who reserve a room online? Test the appropriate hypotheses using a significant level of 0.05

Explanation / Answer

The Z-Score is -1.6669. The p-value is 0.09492. The proportion of Yes or No responses for Observation 1 is 0.712. The proportion for Observation 2 is 0.833.

If the p-value is more than 0.05, we accept null hypothesis that there's difference between the means and conclude that a significant difference does not exist
