Once again, welcome to a new problem.
00:05
This time we're dealing with inferential statistics.
00:12
We're dealing with inferential statistics, and there are two branches to this.
00:17
There is hypothesis testing on one side, and on the other side we also have confidence interval.
00:29
So we have both hypothesis testing and we also have confidence interval.
00:36
We have hypothesis testing for means.
00:39
And we also have hypothesis testing for proportions.
00:44
So we have both means and proportions.
00:48
And for means, we have one sample t tests, one sample t test.
00:56
And we also have two sample t test.
00:59
Two sample t tests and these tests can be independent so we can have an independent independent samples t test or we could have a dependent samples t test and the dependent samples t test is also called the paired samples t test.
01:28
So we're looking at a new problem and in this problem it involves research.
01:38
It involves research on collected data...
