We are asked for this question to provide the frequency table for the data shown here.
00:07
So let's begin with the frequency column.
00:11
We first have to count how many data fall in the 70 to 74 class.
00:19
We have 2, 3, 4, 5, 6, total of 6.
00:28
Then the 75 to 79 class, 1, 2, 3, 80 to 84.
00:39
There's 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
00:57
85 to 89, there's 1, 2, 3, and then the remainder are 90 to 94, so we have 1, 2, 3.
01:12
Now for relative frequency, that's the frequency divided by the total number of data.
01:19
So the total number is 30.
01:23
So all we do is we take every frequency divide by 30, and that's our relative frequency.
01:33
So for the first one, that's 0 .2 and 0 .1, .4667, 0 .1, and 0 .1333...
