Based on this plot, what can you say about the validity of the regression model? Answer Tables Keypad Keyboard Shortcuts O The histogram of the residuals resembles a normal distribution, so the normality assumption of the regression model is satisfied. O The histogram of the residuals resembles a normal distribution, so the normality assumption of the regression model is not satisfied. O The histogram of the residuals does not resemble a normal distribution, so the normality assumption of the regression model is satisfied. The histogram of the residuals does not resemble a normal distribution, so the normality assumption of the regression model is not satisfied.
