[tex]\begin{gathered} Median:140 \\ IQR=3 \end{gathered}[/tex]
1) In this question, we need to remember that in any boxplot the line in the middle of the box indicates the median.
Based on that, we can tell the Median is 140
2) In the Interquartile Range, we need to find the range between the lower quartile and the upper one, based on that boxplot. We can tell the IQR is:
[tex]IQR=Q_3-Q_1\Rightarrow141-138=3[/tex]
Note that the boundaries of the box show us the lower and the upper quartile:
