Answer: A, E, B, and C

Step-by-step explanation:

A regression procedure require all of the following

1. Linearity: The relationship between X and the mean of Y must always be linear. C fulfills this condition

2. Homoscedasticity: Sometimes known as the homogeneity of avariance is always same for any given value of X. A also fulfills this condition.

3. Normality: A fixed values of X, and Y is always normally distributed. B and E fulfills this condition.
