pls help idk what to do

The histogram shows information about the total time, m minutes, taken by each child in
a school to walk to school every day for one week.
There are no children for whom m > 100
There are 10 children for whom m ≤ 20

Work out an estimate for the number of children for whom 50 <m ≤ 80

1st

This might be wrong

but

[bold blaze]

what I did was

Looked for the frequency density

Thats's

Frequency/classwidth

10/20

=0.5

wait a minute its not 465

So if the fd is 0.5 @wide hamlet

Then for 50 <m ≤ 80

We have two bars

Its 119 but wait

u need to split the distance from 50 to 80 into 3 bars
