A researcher designed a study to find out the effectiveness oftwo teaching methods: lecture-style vs. discussion-style. Hecompares the test scores of the students taught with these twodifferent methods. The scores on the test range from 0 to 41 withhigher scores indicating better performance. The test results areprovided in the table below:
                                  Group      Methods                n            M            SS
                                    1           lecture-style         15           24          336
                                    2           discussion-style   15           28            392
- Do students taught with the discussion style performbetter than those taught with the lecture style? Use the.05 significance level for the one-tailed test. Show the four stepsof hypothesis testing, and describe the hypotheses and conclusionin words as well as notations
