Answer:
Solution:-
The grouped frequency table
________________________________________________________
Width (in mm) C.F. Class Interval Frequency ________________________________________________________
≥ 20 50 20 - 30 50 - 44 = 6 ≥ 30 44 30 - 40 44 - 28 = 16
≥ 40 28 40 - 50 28 - 20 = 8
≥ 50 20 50 - 60 20 - 15 = 5
≥ 60 15 60 - 70 15 - 0 = 15
