Quizplus · Accepted Answer

We can use a calculator to find the value of the linear correlation coefficient r, which is approximately 0.863. We can also notice that there is a strong positive linear relationship between the two variables, as higher values of performance are associated with higher values of attitude. This is supported by the value of r, which is close to 1 and indicates a strong positive linear correlation. Therefore, the best choice is C.
