Researchers examined hormonal changes in women during the menopausal years. They found a weak linear relationship between age (in years) and the six-month percent change in plasma level of the reproductive hormone LH. Software gave the following output for the least-squares regression analysis:
Predictor Coef SE Coef T P
Constant 101.46 79.05 1.28 0.207
Age -1.627 1.559 -1.04 0.303
S = 41.5236 R-Sq = 2.9% R-Sq(adj) = 0.2%
Based on this output, what is the equation for the least-squares regression line?
A) LH = 101.46 * age + 79.05
B) LH = 101.46 * age - 1.627
C) LH = 101.46 - 1.627 * age
D) LH = -1.627 * age + 1.559
