All right, so here's the three problems for the stats questions.
00:04
It's three different classes.
00:07
And the first one, the class, there's 20 men and 22 women.
00:10
We want to find what percent of the class is male.
00:13
Well, there's 20 men, but all total there's 42 people.
00:21
So don't do 20 divided by 42.
00:23
Do 20 divided by 40.
00:25
Yeah, don't do 20 divided by 22.
00:27
Do 20 divided by 42.
00:31
When i get 0 .47619 as a percent, it's i don't know how many decimal places they want.
00:39
It's 47.
00:41
We'll go 6190 percent, round to whatever percent they want you to.
00:49
If they want the nearest percent, 48 percent.
00:51
If they want nearest 10th, 47 .6 percent.
00:54
But that's how you find that.
00:56
So now in a different class, there's 267 students.
01:01
54 .3 % of those students are male.
01:06
And so we want to know how many men are in the class.
01:09
Well, you take the total 267, and we're going to times it by 54 .3%, but i'm going to make it a decimal, change it to a decimal.
01:22
And so you go 267 times 0 .543.
01:29
So there's 144 .98, so can't have 0 .98 of a person.
01:35
So we'll say it's approximately more than likely you have a whole person, 145 men in the class.
01:50
And then the rest would be women, 122 would be women...
