Sometimes I just write an N there. And so what is this going to be equal to? First, let's calculate just the margin of error right over here. So this is going to be 2.776 times 1.64 divided by the square root of five. And we get a margin of error of approximately 2.036. So this is going to be 6.8 plus or minus 2.036. It's approximately equal to that, where this is our margin of error.
