And this is a sampling distribution of the sample mean for n is equal to 7. And I won't go into the details here. But when n is equal to 7, you have 6 degrees of freedom, or n minus 1. And the way that t tables are set up, you go and find the degrees of freedom. So you don't go to the n. You go to the n minus 1. So you go to the 6 right here. So if you want to encapsulate 95% of this right over here, and you have an n of 6, you have to go 2.447 standard deviations in each direction.
