Answer
(a) The distribution is symmetric.
(b)
$MINIMUM=-1$
$Q_1=2$
$M=5$
$Q_3=8$
$MAXIMUM=11$
Work Step by Step
(a) The median is in the center of the box. Also, the whiskers are about the same size.
(b) The left whisker begins above the -1 (minimum) and touches the box above the 2 ($Q_1$). The vertical line inside the box is above the 5 (median). The right whisker touches the box above the 8 ($Q_3$) and finishes above the 11 (maximum).
