A frequency distribution of temperatures (in °C) in Shimla is given: 0-5: 3, 5-10: 7, 10-15: 11, 15-20: 6. For the closed frequency polygon, list the x-coordinates (class marks) of the two zero-frequency closing points.

Question

Accepted Answer

-2.5 and 22.5. Add a class -5 to 0 (mark -2.5) before, and 20-25 (mark 22.5) after. So the closing points are at x = -2.5 and x = 22.5.

A frequency distribution of temperatures (in °C) in Shimla is given:
0-5: 3, 5-10: 7, 10-15: 11, 15-20: 6.
For the closed frequency polygon, list the $x$ -coordinates (class marks) of the two zero-frequency closing points.
