question 24

Multiple Choice

Use the following information to answer the question. Can deep-knee bends help you stay alert in class? Forty subjects were
measured for alertness at the beginning of class then voluntarily performed fifteen deep-knee bends followed by a forty-five
minute lecture. Each subject was then measured for alertness at the end of the lecture. The hypothesis test results for the sign
test are summarized below. Assume that all conditions for testing have been met: Hypothesis test results:
Parameter: Median of variable
$\begin{array}{l}H_{0}: \text { median }=0 \\H_{A}: \text { median } \neq 0\end{array}$
$\begin{array}{|l|l|l|l|l|l|l|l|}\hline \text { Variable } & \mathrm{n} & \mathrm{n} \text { for tests } & \text { Sample Median } & \text { Below } & \text { Equal } & \text { Above } & \text { P-value } \\\hline \text { Difference } & 40 & 35 & 1 & 14 & 5 & 21 & 0.4777 \\\hline\end{array}$
-Using a significance level of 5%, state the correct decision regarding the null hypothesis and concluding statement.

• A) Reject \( \mathrm{H}_{0} \). There is evidence to suggest that there is difference in alertness after deep knee bends before the lecture.
• B) Fail to reject \( \mathrm{H}_{0} \). There is evidence to suggest that there is a difference in alertness after deep knee bends before the lecture.
• C) Fail to reject \( \mathrm{H}_{0} \). There is evidence to suggest that there is no difference in alertness after deep knee bends before the lecture.
• D) Reject \( \mathrm{H}_{0} \). There is evidence to suggest that there is no difference in alertness after deep knee bends before the lecture.
