Sophie wanted to know if sons of taller fathers tend to be taller. She collected data about the heights of a random sample of 110 men and about their fathers' heights. Here is computer output from a least-squares regression analysis on her sample: Predictor Coef SE Coef T P Constant 100.64 10.1 9.960 0.000 Father's height 0.431 0.059 7.369 0.000 S = 5.673 R-sq = 21.12% Assume that all conditions for inference have been met. Which of these is a 90% confidence interval for the slope of the least squares regression line? Choose 1 answer: A 0.431 + 1.29(0.059) B 0.431 + 1.645(0.059) c 0.431 + 1.66(0.059) 0.059 D 0.431 + 1.29 110
