The Volumes (In Ounces)of Juice in Eight Randomly Selected Juice $\begin{array} { l l l l } 15.0 & 15.9 & 15.8 & 15.0 \\ 15.7 & 15.4 & 15.9 & 15.4 \end{array}$

The volumes (in ounces) of juice in eight randomly selected juice bottles are as follows: $\begin{array} { l l l l } 15.0 & 15.9 & 15.8 & 15.0 \\ 15.7 & 15.4 & 15.9 & 15.4 \end{array}$
$\begin{array} { l l l l } 15.7 & 15.4 & 15.9 & 15.4 \end{array}$
