M9 Exam Question 1 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. Answer Note that for n=28 and 95% we get a value from the chart of .37389. The absolute of r is |r|=.35, which is below .37389. So no linear relation exists. Question 2 Suppose you have 19 data points and you calculate t...
