Answer :

Less than method, it is given that:



Now we mark the upper class limits along x-axis and cumulative frequency along y-axis. Thus, we plot the points: (7,26); (14,57); (21,92); (28,134); (35,216); (42,287); (49,341); (56,360)


More than method: We will prepare the cumulative frequency table by more than method as given below:



Now we mark,


On x-axis lower class limit and on y-axis Cumulative frequency


Thus, we plot graph as (0,360); (7,334); (14,303); (21,263); (28,226); (35,144); (42,73); (49,19)
