A researcher is interested in determining if convicts' "age" (X) is correlated with the "sentence length" (Y) they receive for non-violent felonies (i.e., years in prison). To determine if an association exists, she randomly selects 10 felons who were convicted of similar non-violent crimes and determines their age and the sentence length they received. Her data is listed below: X (AGE) Y (Sentence Length) 55 3 60 1 20 10 18 6 40 2 35 4 22 9 65 1 70 1 20 15
