step by step ​

Answer 1

Answer:

Construct a histogram for the given data. Mark the mid point of the tops of rectangles of histogram and join these points by line segments. To complete the polygon, mark two classes (−10 to 0) and (80 to 90). Join the end point of the line segments to the mid points of these two classes. The curve so obtained is a frequency polygon.
