In this question we have to find the missing frequencies.
00:04
We are given with the number of families n that is equals to 100.
00:09
Median is equals to 25 and mode here is 29.
00:17
Now let us draw the cumulative frequency distribution table.
00:32
In first, first we will write down the expandager.
00:43
Second is the number of families that is the frequency and in last we will write cumulative frequency.
00:51
So expenditure is 0 to 10, 10 to 20, then 20 to 30, 30 to 40 and last we have 40 to 50.
01:04
So for 0 to 10 frequency is 14.
01:08
0 to 10 frequency 14.
01:10
10 to 20 let frequency is x.
01:14
20 to 30 frequency is given 27.
01:17
30 to 40 let the frequency is y.
01:20
40 to 50 frequency is 15.
01:22
So cumulative frequency will be 14.
01:26
14 plus x.
01:28
Here, 41 plus x...
