So, i see that you need help with this question and so what i'm going to do is it wants you to make a frequency table for the data.
00:10
So, i split up the data into classes with class widths of 10, starting from 20 going all the way to 89.
00:17
And so, the frequency of 20 to 29 is 1.
00:22
Then from 30 to 39, this is going to be 1, 2, 3, and then we have 4, 5, so that's 5.
00:40
Then from 40 to 49, 1, 2, 3, 4, 5, 6, 7, 8, so 9, so that's a total of 9.
00:59
Then we have 50 to 59, so that's 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and then 11, so that's 11.
01:33
And also what i'm noticing is i want to go all the way to 59 .99, okay? and then like 49 .99 and it would be like .999, oops, and then 39 .999, wrong number, and then 29 .999, let me add another digit here, and then 69 .99, oops, 999, and then 79 .999, and then 89 .999.
02:16
And then from 60 to 69 .9, that's 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, so that's 15.
02:44
Then 70 to 79 .999 is 1, 2, and then 3, 4, and then, so that's 4...
