You can put this solution on YOUR website! A random sample contains 50 different burger restaurants in the United States. You ask those restaurants how much they charge for a large burger, and you get a sample mean of $6. Then, you create a confidence interval using this data with the lower limit at $4.50 and the upper limit at $7.50.
---------
Sample mean = x-bar = 6
------
6-ME = 4.5
ME = 1.5
==========
CI:: 6-1.5 < u < 6+1.5
