For the companying data set,
X 2 6 6 7 9
Y 3 2 6 9 5
(a) By hand, compute the correction coefficient. The correlation coefficient is r= (......). (Rounds to three decimal places as needed)
(b) Determine whether there is a linear relation between x and y. Explain.
(c) Find the critical value correlation for the sample size n= 5. Used the table of critical value for correlation coefficient. Explain.
