Answer #1

16) Answer: D) i, ii, and iii

Explanation: The graph shows perfect negative relationship between x and y. Hence all three statements are true.

14) Answer: D) ii only

Explanation: Only ii statement is true because the sample variances resistant to outlier.

13) Answer: B) i)

Explanation: The residual plot (i) indicates that the linear model is good feet for data because the all the point distributed randomly below or above the x axis.
