-When investigating times required for drive-through service, the following results (in seconds) were obtained. $\begin{array}{lllllllll}\text { Restaurant A } & 120 & 123 & 153 & 128 & 124 & 118 & 154 & 110\end{array}$
$\begin{array}{lllllllll}\text { Restaurant B } & 115 & 126 & 147 & 156 & 118 & 110 & 145 & 137\end{array}$
