Explanation / Answer
1. Raw data is not given.
Generally, highest percentage represents that the given data is suitable for linear model
2.Correct Answer: Option(B) - 275
Since C = 50(5) + 25 = 275
3. Correct Answer: Option(A) - 50
4. Actually, Slope of given data is 3.
5. Correct Answer: Option(B) - Slope = 5
6. Correct Answer: Option(B) - 100% chose the given data as linear model
