Verify That the Residuals Are Normally Distributed
-For the least-squares regression model, $y _ { i } = \beta _ { 0 } + \beta _ { 1 } x _ { i } + \varepsilon _ { i }$ , the predictor variable must be normally distributed. To show that this is true, the________ must also be normal.

B) explanatory variable
C) variability
