An education researcher would like to test whether 2nd graders retain or lose knowledge during the summer when they are presumably not in school. She asks nine 2nd graders to take a comprehension exam at the end of the school year (May), and then asks those same students to come back after the summer (late August) to retake a different but equivalent exam, to see if their level of comprehension has changed. Using the data below, test this hypothesis using an (alpha level of .05.) May August 95 100 72 80 78 95 50 65 89 85 92 98 75 70 90 96 65 87 What is the appropirate test? Null Hypothesis? Alternative Hypothesis Critical Value(s) Obtained statistic Make a decision and what does it mean Please use SPSS software to confirm results
