You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: \begin{tabular}{|r|r|} \hline pre-test & post-test \\ \hline 28.9 & 30.1 \\ \hline 55.1 & 61.1 \\ \hline 39.6 & 37.4 \\ \hline 35.6 & -0.9 \\ \hline 52.5 & 49.6 \\ \hline 47.8 & 36.9 \\ \hline 45.3 & 31 \\ \hline 39.2 & 40.8 \\ \hline 36.5 & 37.3 \\ \hline 26.3 & 24.5 \\ \hline 44.5 & 8 \\ \hline 34.1 & 42.3 \\ \hline 35.1 & 61.3 \\ \hline 60.5 & 52.6 \\ \hline 50.7 & 49.3 \\ \hline 44.2 & 60.7 \\ \hline 52.1 & 80.9 \\ \hline \end{tabular}
