Answer 1

Construction of frequency polygon:

MARKS            STUDENTS               MIDPOINT

50-52                    4                                 51

47-49                    10                                48

44-46                    15                                45

32-34                     13                                 33

Frequency polygon is constructed by taking midpoints on X-axis and

frequencies on Y-axis
