A hotel chain wants to determine whether there is a difference in the length of stays at two of its different brands of hotels. A simple random sample of 100 stay lengths was taken for each hotel brand. These data are shown below. Assume that the variances are not equal. a) State the appropriate null and alternative hypotheses. b) Based on these sample data and an alpha .05 level of significance, what conclusion should be made about the average length of stay at these two hotel chains? Calculate the test statistic. The test statistic is (Round to two decimal places as needed.) Calculate the p-value. The p-value is (Round to four decimal places as needed.) d. State the conclusion for this hypothesis test.
