Question 282203: If you are constructing a 95% confidence interval using the information:
n=55, x-bar = 55.5, s = 2.1, and E = 0.65
What is the middle value of the interval?

The middle value should be x-bar, you find the radius of the interval and then you plus it with x-bar and minus it with x-bar so x-bar would be the middle of it ;)
