Select all that apply. A. All of the assumptions and conditions for multiple regression appear to be met. B. The independence Assumption cannot be checked using the provided plots. C. The Randomization Condition is not met. Since the data was not collected through a random sample. D. The Linearity Condition is not met. because there is a nonlinear pattern in the plot of residuals against predicted values. E. The Nearly Normal Condition is not met, because the histogram suggests that there are several outliers to the right. F. The Equal Variance Condition is not met, because the spread of the residuals is not constant. G. The independence Assumption is not met. since the residuals exhibit a negative-positive-negative pattern. Click to select your answer(s).

Explanation / Answer

The assumptions that apply is :

(D) The linearity condition is not met, because there is a non-linear pattern in the plot of residuals against predicted values.

(E) The nearly normal condition is not met, because the histogram suggests that there are several outliers to the right.

(G) The independence assumption is not met, since the residuals exhibit a negative-positive-negative pattern.
