SECTION 3

A survey claims that the average cost of a hotel room in Atlanta is greater than $69.23. To test this claim, a researcher selects a sample of 30 hotel rooms and finds the average cost is $68.43. Assume the population standard deviation of $3.72. At a 0.05 significance level, is there enough evidence to support the claim that the average cost of a hotel room in Atlanta is greater $69.23?

• What is the null hypothesis? A. Ho: 69.23 b. Ho: 69.23 c. Ho: = 69.23
• What is the alternative hypothesis? A. Ha: > 69.23 b. Ha: 69.23 c. Ha: < 69.23
• What is the test statistic? Round the answer to two decimal places.
• What is the p-value? Round the answer to three decimal places.
• What is the conclusion when you compare the p-value and the level of significance (alpha)? a. reject the null hypothesis b. Fail to reject the null hypothesis
• What is the conclusion based on the original claim? A. At the 0.05 level of significance, the cost of a hotel room in Atlanta is not greater than $69.23. B. At the 0.05 level of significance, the cost of a hotel room in Atlanta is greater than $69.23
