The prices of a random sample of comparable (matched) textbooks from two schools were recorded. Assume that the population distribution of differences is approximately Normal, and assume that the sampling was random. Each book was priced separately; there were no books "bundled" together. a. Compare the sample means. b. Determine whether the mean prices of all books are significantly different. Use a significance level of 0.05. Click the icon to view the table of prices. a. Find the sample mean for University A. (Round to the nearest cent as needed.) Find the sample mean for University B. (Round to the nearest cent as needed.) Compare the sample means. The sample mean is larger at b. Determine the hypotheses for this test. Let HA be the population mean price for books at University A, and let le be the population mean price for books at University B. Use Hdifference =PA - PB- Choose the correct answer below. O A.

What is the unit of observation in this sample?b. What is the variable collected?c. Draw and label the histogram for this dataset.d. Which is the modal category?e. Calculate the proportion of the salespeople made 9 or more sales.f. Calculate the number of salespeople who made between 0 and 9 sales.
