You work for an online retailer. Your colleague asserts that the average review scores from Canadian buyers are at least 0.2 greater than those of American buyers. You want to test this! You take samples of reviews from both Canadian and American customers; data for the two samples are given in the Excel file. Test the hypothesis that the mean for Canadians is at least 0.2 greater than that of Americans, at the 95% confidence level. Show all parts of the hypothesis test, including your hypotheses, identification/calculation of the necessary values, your test-statistic calculation, your p-value calculation, and your conclusion. For this question, you may use the appropriate Analysis Toolpak tool.
