This problem, we are given with a relative frequency table.
00:03
Let us draw the table here.
00:05
In the table we have value and the relative frequency.
00:11
The relative frequency of the given value.
00:15
And the values are 4, 5, 6 and 7.
00:19
Relative frequency values are 0 .35, 0 .20, 0 .05 and 0 .40 .0 .05 and 0 .40.
00:28
Now for the given relative frequency values and normal values, we are asked to find out the cumulative relative frequency table here.
00:39
In order to find out the cumulative relative frequency, we should know one formula.
00:43
That is, let us assume that the cumulative relative frequency short form is crf, which is is equals to relative frequency of past plus relative frequency of present.
00:58
That is, if we are finding the relative frequency of this value 5, we will be adding the 0 .2 with 0 .35.
01:08
Since the present value is 0 .2 and past value is 0 .35.
01:13
Therefore, relative frequency past plus relative frequency present.
01:16
That gives the cumulative relative frequency here.
01:19
Therefore, the cumulative relative frequency values will be rf, crf.
01:26
Now, rf is 0 .35...
