Convert the given appropriation table to a not as much as type aggregate recurrence circulation, and we get
Every day income Frequency Cumulative Frequency
Under 120 12 12
Under 140 14 26
Under 160 8 34
Under 180 6 40
Under 200 10 50
From the table plot the focuses comparing to the arranged combines, for example, (120, 12), (140, 26), (160, 34), (180, 40) and (200, 50) on chart paper and the plotted focuses are joined to get a smooth bend and the got bend is known as not as much as type ogive bend
