The estimated regression equation for a model involving two independent variables and 10 observations follows. Here SST = 6,724.125, Interpret the regression coefficients in this estimated regression equation Group of answer choices A one-unit increase in x1 will lead to a 0.5906 unit increase in y, when x2 is held constant. A one-unit increase in x2 will lead to a 0.498 unit decrease in y, when x1 is held constant.
