Suppose you have 28 data points and you calculate the sample correlation coefficient and find that r = .35. Can you be 95% confident that a linear relation exists between the variables? If so, is the relation positive or negative? Justify you answer. Your Answer: n=28 r=.35 Critical Value = 0.37389 We can be 95% confident that a postive linear relation exists between the variables because the absolute of r= .35 and that is greater than the critical value of 0.37389
