Expert Solution & Answer
To determine
The value of the sample correlation coefficient when the scatter diagram shows no linear relationship between x and y.
Answer to Problem 1CR
Solution: The sample correlation coefficient is close to 0.
Explanation of Solution
The range of the value of the correlation coefficient (r) is
So, if the scatter diagram shows that there is no linear relationship between x and y, then the value of the sample correlation coefficient is expected to be near to 0.
