A sample of Greendale university students takes a stats exam and their scores are summarized below. If the mean for the general Greendale population on this test is u = 12, can we conclude that these students are significantly different from the population? Use a two-tailed test with a=.01. Showing work for calculating s’ s, and t and list conclusions. M2 Scores: 16, 18, 20, 15, 12 Step 1 (what is it): H: H;: Step 2 (what is it) Critical region: Step 3 (what is next): s' = S,= t = obt step 4 (what is it): do we reject or fail to reject ? Can you conclude that these students are significantly different from the population? what is cohens D? what are results in APA ?
