So in this question we need to find the critical values for t alpha with a specific degrees of freedom.
00:07
So this t represents the t, the student distribution.
00:12
So i'm going to call this the t distribution.
00:15
This is the right area that we have to the value that we want.
00:20
And this is our, this one represents the degrees of freedom, okay? which is they already given for each one of the items.
00:32
So in this case, like i said, we are interested, this is the shape that we have for the t distribution.
00:41
And the value that we are interested in is the value that has this right area equals to alpha.
00:47
So i need to use the t table, which will usually provide the left area, which is 1 minus alpha, since the total area means to sum up to 1.
00:56
And you can use this or if you have a table that provides the right area to find the value that we need...
