We have it right over here, 99%. We have 9 degrees of freedom. We have 10 data points, 10 minus 1 is 9. 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.
