1. Suppose vou have 45 data points and vou calculate the sample correlation coefcient and find that r = .32. Can vou be 95% condent that a linear relation exisLs between the variables? If so. is the relation positive or negative? Justify:r vou answer. Note that for n=45 and 95% we get a value from the chart of .29396. The absolute of r is | r | =32, which is above .29395. So a positive linear relation exists
