For the Following Data, Compute the Test Statistic and the Critical

Multiple Choice

For the following data, compute the test statistic and the critical value, and determine whether to reject $H _ { 0 }$ at the $\alpha = 0.05$ level.
$\begin{array} { l | l | l | l | l | l | l | l | l | l | l } \text { Sample A } & 76 & 61 & 71 & 80 & 77 & 78 & 63 & 60 & 77 & 79 \\\hline \text { Sample B } & 65 & 42 & 71 & 84 & 70 & 78 & 49 & 51 & 90 & 65\end{array}$

A) S=7 , Critical value is 4, Do not reject $H _ { 0 }$
B) S=6 , Critical value is 8, Reject $H _ { 0 }$
C) S=7 , Critical value is 4, Reject $H _ { 0 }$
D) S=6 , Critical value is 8, Do not reject $H _ { 0 }$
