A travel analyst claims that the mean of the room rates for two adults at three-star hotels in Salt Lake City is $134. In a random sample of 37 three-star hotels in Salt Lake City, the mean room rate for two adults is $143. Assume the population standard deviation is $30. At is there enough evidence to reject the analyst's claim? a) Identify the claim and state the and b) Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed, and whether to use a z-test or a t-test. Explain your reasoning. c) Choose one of the options: a. Option 1: Find the critical value(s) identify the rejection region(s) by drawing a sketch, and find the appropriate standardized test statistic. b. Option 2: Find the appropriate standardized test statistic and the P-value by drawing sketch. d. Decided whether to reject or fail to reject the null hypothesis. e. Interpret the decision in the context of the original claim.
