It Was Thought That Hypnosis Would Lower a Person's Need $\alpha = 0.5$

Multiple Choice

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?
$\begin{array}{ccc}\hline \text { Subject } & \begin{array}{c}\text { Before Hypnosis } \\\text { cigarettesfday }\end{array} & \begin{array}{c}\text { After Hypnosis } \\\text { cigarettes/day }\end{array} \\\hline 1 & 18 & 16 \\2 & 20 & 18 \\3 & 25 & 25 \\4 & 15 & 10 \\5 & 19 & 20 \\6 & 21 & 23 \\7 & 30 & 26 \\8 & 16 & 15 \\9 & 13 & 14 \\10 & 20 & 18 \\\hline\end{array}$

A) The critical value is less than the test value; therefore, there is not enough evidence to support the hypothesis.
B) The critical value is greater than the test value; therefore, there is not enough evidence to support the hypothesis.
C) The critical value is less than the test value; therefore, there is enough evidence to support the hypothesis.
D) The critical value is greater than the test value; therefore, there is enough evidence to support the hypothesis.
