Students at University A are concerned about the high costs of textbooks at their school's bookstore and they believe that they pay more, on average, for textbooks than students at University B. In a sample of 50 students from University A the average amount of money spent on textbooks for this past semester was $260. In a sample of 40 students from University B the average amount of money spent on textbooks for this past semester was $250. The population standard deviation for textbook purchased at University A is $21 and the population standard deviation for textbooks purchased at University B was $23. At the 5% significance level, determine if the students at University A spend more on average for textbooks than students at University B.
