The sums have been evaluated. Solve the simplified system for a and b to find the least squares regression line for the points. Use a graphing utility to confirm the result. (Note: The symbol E is used to denote a sum of the terms of a sequence. You will learn how to use this notation in Section 9.1. Round all numerical values to two decimal places.) 56 + 10a = 20.4 10b + 30a = 50.8 6 ( 4 , 5.9 ) a ( 3 , 5 .3 ) (2, 2.1) (1, 2.9 ) (0, 2.1) 2 Need Help?
