SOLUTION:
Case: Checking conditions for linear model
Given: A plot of points given in a graph
Required: State if any condition for linear model is violated
Method: The conditions for a linear model includes:
1. Quantitative Data Condition: Check if there is a constant (repeated) addition or subtraction pattern
2. The linearity Condition: That the graph is straight enough
3. The Outlier Condition: That it is free of outliers
4. Independence of Errors: If a table is given, it is independent of errors.
Final answer:
The answer is (C) As the residuals do not display a constant variance error
