In a fitted simple linear regression model,the quantity that estimates the amount by which the mean of Y (dependent variable)changes for a unit change in X (independent variable)is called the _____.
A)coefficient of determination
B)slope of the regression line
C)y intercept of the regression line
D)correlation coefficient
E)standard error

The slope of the regression line estimates the amount by which the mean of Y changes for a unit change in X, making it the best choice out of the options given. The coefficient of determination (A) measures the proportion of variation in the dependent variable that is explained by the independent variable. The y intercept (C) is the predicted value of Y when X is 0. The correlation coefficient (D) measures the strength and direction of the linear relationship between X and Y. The standard error (E) measures the variability of the residuals around the estimated regression line.
