Given the following data, test the claim that there is a linear correlation between drug dosage and heart rate. Drug Dosage (mg) 0.125 0.20 0.25 0.30 0.35 0.40 0.55 Heart Rate (beats per minute) 95 88 90 91 85 80 78 Question content area bottom Part 1 What conclusion can be drawn? Use alpha equals 0.05 . A. r = -0.9138 There is no significant linear correlation which means drug dosage and heart rate are not related. B. r = 0.8350. There is no significant linear correlation which means drug dosage and heart rate are not related. C. r = -0.8350. There is significant negative linear correlation which means as drug dosage increases heart rate decreases. D. r = -0.9138. There is significant negative linear correlation which means as drug dosage increases heart rate decreases
