Answer» In the given data, the highest frequency is 26, which is lies in the interval 201-202 Here, `l=201, f_(m)=26, f_(1)=12, f_(2)=20 and ("class width")h=1` `therefore "Mode"l+((f_(m)-t_(1))/(2f_(m)-t_(1)-f_(2)))xxh=201+((26-12)/(2xx26-12-20))xx1` `=201+((14)/(52-32))=201+(14)/(20)=201+0.7=201.7g` Hence the modal weight is 201.7g |
