The results below are based on data collected as part of a student project for an introductory statistics class at UF. If there is more than one group/treatment, the first group mentioned is group 1. Data was collected at two local bookstores to determine if the average price of new textbooks was significantly lower at an Independent Bookstore than at the UF Bookstore. The p-value was 0.00, and the 95% confidence interval was ( -11.98, -4.52). The students selected textbooks at random from the online list of books required for UF courses. Then the price for each book was found at both stores. This problem is about two independent means . The sign of the alternative hypothesis should be . Based on the p-value we can at alpha = 0.05. At which alpha levels could we Reject Ho? Are the results statistically significant at alpha=0.01? We have to say that the average price of new textbooks at the Independent Bookstore is lower than at the UF Bookstore. We are 95% confident that the average price of new textbooks at the Independent Bookstore is between than at the UF Bookstore. The results of the confidence interval and significance test at alpha=0.05
