The historical mean for the final exam of a math course is 80, with a population standard deviation of 3. This year, a new teaching method is used to teach the same course, and the average final exam grade is 81. Based on this data, can we say that the new teaching method is better than the previous one (using an alpha level of .05)? Use the data in the GRADES spreadsheet to answer. Make sure you have the complete solution, from hypothesis formulation to reaching a conclusion. What is your conclusion?
