This value right here, let me get the calculator out just to get a value in place there. This is going to be 17.17 minus 20, close parentheses, divided by 2.98 divided by the square root of 10, and then close parentheses. It is almost exactly negative 3. Our t statistic is almost exactly negative 3. Negative 3.00. What we need to figure out, because t statistics have a t distribution, what we need to figure out is the probability of getting this t statistic, or a value of t equal to this or less than this, is that less than 1%. The way we can think about it is we have a t distribution.
