Question 2

It was thought that hypnosis would lower a person's need to smoke. A researcher decided to investigate this hypothesis using the paired-sample sign test. Given that the critical value for ten samples at $\alpha = 0.5$ (single-sided) is 1, is there enough evidence to support the hypothesis?
$\begin{array}{ccc}
\hline \text { Subject } & \begin{array}{c}
\text { Before Hypnosis } \
\text { cigarettesfday }
\end{array} & \begin{array}{c}
\text { After Hypnosis } \
\text { cigarettes/day }
\end{array} \
\hline 1 & 18 & 16 \
2 & 20 & 18 \
3 & 25 & 25 \
4 & 15 & 10 \
