It's approximately equal to that, where this is our margin of error. And if we actually wanted to write out the interval, we could just take 6.8 minus this and 6.8 plus that. So let's do that again with the calculator. 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.
