Answer 2

Given,

A) There is a linear relationship between the independent and dependent variables.

B) The residual variation is the same for all fitted values of Y.

C) The residuals are normally distributed.

D) Successive observations of the dependent variable are uncorrelated.

To find,

If Time Is Used As An Independent Variable In A Simple Linear Regression Analysis, Which Of The Following Assumptions Could Be Violated?

Solution,

If we take time as an independent variable in simple regression analysis, the assumption:

A) There is a linear relationship between the independent and dependent variables could not be violated.

B) The residual variation is the same for all fitted values of Y could not be violated.

C) The residuals are normally distributed could not be violated.

D) Successive observations of the dependent variable are uncorrelated could be violated.

Hence, (D) Successive observations of the dependent variable are uncorrelated is the correct option.
