Problem 29E
Suppose you fit a least squares line to 26 data points and the calculated value of SSE is 8.34.
a. Find s2, the estimator of s2 (the variance of the random error term e).
b. What is the largest deviation that you might expect between any one of the 26 points and the least squares line?

b. What is the largest deviation that you might expect between any one of the 26 points and the least squares line?
ANSWER:
Step 1 of 2
The given information is as follows:
The number of data points, n = 26
The value of SSE is 8.34
a) We ?nd the value of is,
The formulae for is given by,
Therefore, the value of is 0.348
