Draw the frequency curve

Draw the frequency curve for the following:

Class Interval	Frequency
5-15 15-25 25-35 35-45 45-55 55-65 65-75	18 34 48 72 52 37 14

Inference:

i) The higher frequency for the class interval 5-15

ii) The lowest frequency for the class interval 65-75

iii) Hence, the trend in increased upto 35-45 and started decreasing till 65-75
