Notice that this is a one-sided distribution. We care about this is 1%, and then all of this stuff over here is going to be 99%. Just the way most t tables are set up, they don't set up a negative t value that is oriented like this. They'll just give you a positive t value that's oriented the other way. The way t tables, and I have one that we're going to use in a second right over here, the way t tables are set up is you have your distribution like this, and they will just give a positive t value. They will give a positive t value over here, some threshold value, where the probability of getting a t value above that is going to be 1%, and the probability of getting a t value below that is going to be 99%. You can see that we know t distributions are symmetric around their mean, so whatever value this is, if this number is 2, then this value is just going to be negative 2.
