So you filled in the class midpoint frequencies, so you get 7 ,499 .5, 22 ,499 .5, the next one 37 ,499 .5, and then 52 ,499 .5.
00:28
So these are the midpoints.
00:31
Now we need to fill in the frequency.
00:33
Frequency.
00:34
So given the fact we've got the first one 46, we just need to fill in the next three.
00:44
Okay.
00:50
So given the fact the cumulative frequency is 98, this is going to be 98 minus 46, which is equal to 52.
01:04
Okay.
01:05
And the cumulative frequency goes up to 200 here.
01:09
So this is 46 here.
01:12
Just the filling here.
01:14
We need to fill in this box here.
01:19
Following that.
01:21
So given the fact we go from 200 to 98 here, the difference here is 102.
01:28
Okay...
