One of the questions asked to compute a margin of error for a least squares regression of 7 points. (on the graph).I used a t distribution with df = 6 (because there were 7 points). However, the answer key used df = 5 and specifically stated that using df = 6 is partially correct. I don't understand why it is correct to use df = 5. The computer output included this: Source DF Regression 1 Residual 5 Total 6 Thanks in advance.   | ||
