The box of the diagram is determined by the values of the first and third quartiles. The line inside the box represents the median of the sample, so:
Q₁= 56
Median= 82
Q₃= 125
The left whisker is drawn from the first quartile to the minimum value, so the minimum value of the sample is 33
The right whisker is drawn from the third quartile to the maximum value of the sample, so the maximum value is 185
The interquartile range is the difference between the first and second quartile. It represents the middle 50% of the data set.
With all of this in mind, the only statement that corresponds to this box-and-whisker plot is the first one, since the maximum value of the data set is 185.
Correct option is "a"
