Hey there, welcome to numerate.
00:03
So we have a critical value table for a t distribution.
00:10
Okay, so let's define why we need a t critical for.
00:14
So t critical, usually denote it as t critical with asterisk or is denoted as t alpha, right? alpha or it could be alpha devalued 2.
00:28
Okay, but in this case, it would just be alpha.
00:30
Okay, so those are two ways.
00:33
And so we find t critical basically is to find the critical region to reject the no hypothesis and compare that to our t score.
00:43
So let's say that.
00:45
We compare our t critical, which is our critical, critical value to the t score, or the t score, or the only address as t -statt...
