Some straightforward but slightly tedious algebra shows that from which it follows that se B n 1 n 2 121 r2 2sy Unless n is quite small, (n 1)/(n 2) 1, so a. For what value of r is se as large as sy? What is the equation of the least-squares line in this case? se 121 r2 2sy b. For what values of r will se be much smaller than sy?
