Sorry but, as you saw in the "Read Before Posting" thread that you read before posting, we need to see what you've tried, first. Then we'll provide assistance in getting you unstuck.

Let's start with the definitions and relationships you were taught in class. What is your understanding of the definitions of "confidence interval", "confidence level", and "margin of error"? How do these relate, if at all, to regression models? (For instance, what has your class covered along the lines of what is explained here?)

Please be complete. Thank you!
