as points to be plotted are wrong x coordinate= Lower limit of class y coordinate= corresponding CF SO PAIRS ARE (15,10) (20,25) (25,42) (30,54) (35,64) (40,72) now plot this point and join.... otherwise scale is perfect in graph

your graph is not proper
as points to be plotted are wrong
x coordinate= Lower limit of class
y coordinate= corresponding CF
SO PAIRS ARE
(15,10)
(20,25)
(25,42)
(30,54)
(35,64)
(40,72)
now plot this point and join.... otherwise scale is perfect in graph
