In this question we have some survey data.
00:03
Currently we have the frequency, we want to turn it into relative frequency.
00:08
So we're going to have different responses which i will call x, the frequency, the relative frequency.
00:16
So different options.
00:18
We have the probability of losing jobs in the next year.
00:22
Some said very likely, some said fairly likely, some said not too likely, and some said not likely at all.
00:35
Okay and the frequencies given are 3, 3, 8, 3, 90, 1, 8, 5, 9, and 4 ,836.
00:49
So we want to turn this into relative frequency.
00:53
To go from frequency to relative frequency all we need to do is divide by n, the total number of people in the survey.
01:04
So let's add up these to get a total frequency.
01:09
So n is, just adding these four numbers up, we get 7, 4, 2, 3...
