For questions below, use the following: A researcher predicts that training on the balance beam reduces reading errors among learning disabled youngsters. A random sample of 9 children was selected from the population of learning-disabled children from a large metropolitan school district. They were all given a reading test and their errors recorded. They were then trained on the balance beam for one year, and again their error scores on the reading test recorded. The data follows: $$\begin{array} { c c l }
\text { Subject \#}& \text {Before } & \text { After } \
1 & 12 & 10 \
2 & 12 & 10 \
3 & 2 & 1 \
4 & 6 & 4 \
5 & 6 & 5 \
6 & 7 & 7 \
7 & 10 & 9 \
8 & 9 & 8 \
9 & 11 & 8
\end{array}$$
-As a one-tail test, should Ho be rejected? If rejected, state the alpha level.
