Question 2 a) What is the standard error of estimate, and what role does it play in simple linear regression and correlation analysis? b) Is it possible for the standard error of estimate to be equal to zero? If so, under what circumstances? c) Differentiate between a confidence interval and a prediction interval. d) For a given value of X, which will be wider, a 95% confidence interval or a 95% prediction interval? Explain. e) What happens to the width of a prediction interval for y as the x value on which the interval estimate is based gets farther away from the mean of x? Why?
