9 degrees of freedom. Our threshold t value here is 2.821, so our threshold t value in the case that we care about, just flip this over, it's completely symmetric, is negative 2.821. What this tells us is the probability of getting a t value less than negative 2.821 is going to be 1%. Now, we got a value that's a good bit less than that. We got a t value of negative 3. We got a t value right here, our t statistic of negative 3 right over here. That definitely goes into our, I guess you could call it our area of rejection.
