Answer:
The correct option is C. The first quartile of the data displayed in this box-and-whisker plot is 37.
Step-by-step explanation:
In a box plot,
Point 1: Left end point of the line represents the minimum value of the data set.
Point 2: Left side of the box represent first quartile (Q₁) of the data set.
Point 3: Line inside the box represents Median of the data set.
Point 4: Right side of the box represent third quartile (Q₃) of the data set.
Point 5: Right end point of the line represents the maximum value of the data set.
From the given box-and-whisker plot it is clear that left side of the box is at 37, So, the first quartile of the data displayed in this box-and-whisker plot is 37.
