We need to figure out a threshold t value there. This is for a t distribution that has n equal to 10, or 10 minus 1 equals 9 degrees of freedom. What is that threshold value over there? 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.
