Start by typing the numbers: 4 (for the box that reads "Min" since the list of values (which they gave you already ordered from least to largets) is showing that the minimum value of your set is 4.
You can do the same with the number 16, placing it as the maximum "Max".
AT the same time, it seems that you can move the different parts of the box diagram, so please, grab the left end of the whisker of the box diagram, and move it to align with the number "4" in the horizontal axis.
Do also an adjustment of the right end of the whisker and take it to align with the number 16 in the horizontal axis.
The Median in this case (of even number of values in the set) is given by the average of the two numbers around the middle of the list. So you do : (6+9)/2 = 15/2 = 7.5
7.5 is the median.
The first quartile is for value 6, and the third quartile for the value 10.
So, please move the ends of the box to align with the numbers 6 and 10 on the horizontal axis, and the center of the box
