The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day: A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 37.5 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50. Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points) Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents. (

    The box and whisper plot shows all quantities shown in the graph above. It does not show frequency.

    Part A is done above Part B: Interquartile range = third quartile - first quartile = 60 - 37.5 =22.5

    You wrote a problem. You described the plot. Then you ask Part A and Part B. I answered both parts. There is no part C.
