Question 1 What is the equation of the least-squares regression line? S = 1.532 R-Sq = 60.032 % R-Sq (adj) = 58.621 % Choose 1 answer: y ^ = 0.164 + 2.544 x , where x represents caffeine intake and y represents hours spent studying A y ^ = 0.164 + 2.544 x , where x represents caffeine intake and y represents hours spent studyingYou are given the information to find b1, b 1, and once you have that, you can solve to find b0. b 0. Then you can write the 'least-squares' (estimated) regression line as. Y^i =b0 +b1Xi. Y ^ i = b 0 + b 1 X i. Prediction.
