Q: Answer-In a simple linear regression model, Y = a + bX + e, the coefficient 'b' represents:

In the regression equation Y a bX e a is the intercept -- the expected value of Y when X is 0 option a describes a. b is the slope coefficient . It quantifies the marginal effect for a one-unit increase in the independent variable X, the dependent variable Y is expected to change by b units, on average, ceteris paribus all else held constant . e is the error term option c. Standard deviation and correlation are measures of dispersion and association, not regression coefficients options d e.
