So 6.8 minus 2.036 is equal to 4.764. So our confidence interval starts at 4.764 approximately. And it goes to, let's see, I could actually do this one in my head. If I add 2.036 to 6.8, that is going to be 8.836. Now, how would we interpret this confidence interval right over here? One way to interpret it is to say that we are 95% confident that this interval captures the true mean difference in snaps for these friends. We could also say that there appears to be a difference in the mean number of snaps, since zero is not captured in this interval.
