Independent random samples taken on two university campuses revealed the following information concerning the average amount of money spent on textbooks during the fall semester. The sample standard deviations are provided below. The df = 45 University A University B Sample Size 50 40 Average Purchase $265 $255 Sample Standard Deviation(s) $25 $20 We want to determine if, on the average, students at University A spent more on textbooks then the students at University B. Test at 95% confidence to determine if the students at University A spent more on textbooks than students at University B. What is your decision and conclusion? May use either CV or p-value approach. (indicate your hypotheses, test statistic steps for CV or p-value approach, indicate alpha, CV, PV, TS values in comparison-- and indicate if we should reject or fail to reject Ho and conclusion...are students at University A paying more for books than students at University B??) In your PV and CV comparisons, include values in your comparisons and clearly label the PV value, alpha value, TS value, and CV value. May use either CV or p-value approach If not sure of how to do the problem, take a GUESS at reject or fail to reject and take a GUESS for the conclusion
