If the Test Value for a Signed-Rank Test Is 18 $\alpha = 0.05$

question 26

Multiple Choice

If the test value for a signed-rank test is 18, the sample size is 13, and the test is to be carried out at the $\alpha = 0.05$ level of significance, should the null hypothesis be rejected? Use the table of critical
Values for the signed-rank test below.
$\begin{array} { c | c c c c } \boldsymbol { n } & \alpha = 0.10 & \alpha = 0.05 & \alpha = 0.02 & \alpha = 0.01 \\\hline 9 & 8 & 6 & 3 & 2 \\10 & 11 & 8 & 5 & 3 \\11 & 14 & 11 & 7 & 5 \\12 & 17 & 14 & 10 & 7 \\13 & 21 & 17 & 13 & 10\end{array}$

• A) Reject H₀ because the test value 18 is less than the critical value 20 .
• B) Do not reject H₀ because the test value 18 is less than the critical value 20 .
• C) Reject H₀ because the test value 18 is greater than the critical value 17 .
• D) Do not reject H₀ because the test value 18 is greater than the critical value 17 .
