Ten Functionally Illiterate Adults Were Given an Experimental One-Week Crash

question 71

Essay

Ten functionally illiterate adults were given an experimental one-week crash course in reading. Each of the 10 was given a reading test prior to the course and another test after the course. The results are shown below. $$\begin{array} { | l | c | c | c | c | c | c | c | c | c | c | } \hline \text { Adult } & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\\hline \text { Score after course } & 48 & 42 & 43 & 34 & 50 & 30 & 43 & 38 & 41 & 3 \\\hline \text { Score before course } & 31 & 34 & 18 & 30 & 44 & 28 & 34 & 33 & 27 & 32 \\\hline\end{array}$$ Is there enough evidence to infer at the 5% significance level that the reading scores have improved?
