Twenty-one individuals from a rural Midwestern town took a multiple-choice test that asked about historical events, science, art, literature, and the like. The maximum possible score on the test was a 40. A higher value indicates greater cultural literacy. In a large nationally representative sample, the average score on the same test was a 27. Is the score for the Midwestern sample significantly lower than this? In addition please find these values: Sample Mean= Sample S.D.= Population Mean= S.E.= N= D.F.= t-obtained= alpha= p-value=
