The Statistics Department has an undergraduate program learning objective that focuses on correctly identifying various concepts in designs of experiments. As its benchmark assessment, students take a pre-test and a post-test that bracket the unit of study. Assistant Dean Adele Stacy sampled recent paired scores for nine (9) randomly selected undergraduates. She wondered if scores improved after the routine curricular intervention. Should Dean Adele report a statistically significant finding? Explain. She tested her claims at the 2% level of significance.

Perhaps there an app for this in Excel? Yes, indeed. State the hypotheses; a verbal version is satisfactory; also state the conclusions, both technical and contextual. Express the p-value as you explain your findings. Constructing a corresponding confidence interval to affirm your conclusion can earn bonus credit, though if your testing is one tailed, do create a bogus second tail so to use two-tailed methods.]
