Okay, so we will look at two different ways to know if two means are equal.
00:07
So the first way to know if two means are equal is we can do hypothesis testing.
00:14
So hypothesis testing.
00:21
So our no hypothesis might be that the mean of population one is equal to the mean of population two, to the mean of population two.
00:31
And an alternative hypothesis might be that they're different.
00:37
The means of the two population are different.
00:40
So we can do this.
00:42
Once we have our hypothesis, there are two ways to figure, to deal with our hypothesis.
00:51
So we can use the p value method.
00:56
What's the p value method? well, you compute the z, the z statistic, the z variable.
01:02
Then you compute your p value, so find z...
