In New York City the average hotel room costs $234 per night, with a standard deviation of $65. Suppose that you walk into a random hotel and learn their rate is $155 per night. If the rates are normally distributed, what is the probability that if you leave and walk into another random hotel, they will have a lower rate?
Question 2 Item 2 A travel company is investigating whether the average cost of a hotel stay in a certain city has increased over the past year. The company recorded the cost of a one-night stay for a Friday night in January of the current year and in the previous year for 31 hotels selected at random. The difference in cost (current year minus previous year) was calculated for each hotel. Which of the following is the appropriate test for...
In order to determine the average price of hotel rooms in Atlanta, a sample of 64 hotels was selected. It was determined that the average price of the rooms in the sample was $108.50. Let the population standard deviation of room price be $16. a. (6 points) Formulate the hypotheses to determine whether or not the average room price is significantly different from $112. b. (7 points) Compute the test statistic. c. (7 points) At 99% confidence...
In order to determine the average price of hotel rooms in Atlanta, a sample of 53 hotels were selected. It was determined that the test statistic (z) was $1.79. We would like to test whether or not the average room price is significantly different from $110. Population standard deviation is known to us. Compute the p-value.
