So 9 degrees of freedom for our 10 data points. We just took 10 minus 1. So if we look over here, for that type, so for a t distribution with 9 degrees of freedom, you're going to have 95% of the probability is going to be contained within a t value of, so the t value is going to be between negative. So this value right here is 2.262. And this value right here is negative 2.262. That's what this right here tells us. That if you contain all the values that are less than 2.262 away from the center of your t distribution, you will contain 95% of the probability.
