The weights of coffee im 70 packets are shown in the following table

Determine the modal weight.

Explanation

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
