Musa is interested in the relationship between hours spent studying and caffeine consumption among students at his school. He randomly selects 20 students at his school and records their caffeine intake (mg) and the amount of time spent studying in a given week. Here is computer output from a least-squares regression analysis on his sample: Predictor Coef SE Coef T P Constant 2.544 0.134 18.955 0.000 Caffeine 0.164 0.057 2.862 0.010 S = 1.532 R-sq = 60.0% Assume that all conditions for inference have been met. Which of these is a 95% confidence interval for the slope of the least squares regression line? Choose 1 answer: A 0.164 + 2.101(0.057) K B 0.164 + 1.96(0.057) c 0.164 + 1.734(0.057) D 2.544 + 2.101(0.134)
