The article "Behavioural Effects of Mobile Telephone Use During Simulated Driving"t reported that for a sample of 20 experimental subjects, the sample correlation coefficient for x = age and y = time since the subject had acquired a driving license (yr) vas 0.97. Why do you think the value of r is so close to 17 (The article's authors give an explanation.) O The younger a subject is, the more time since they acquired their license. O The older a subject is, the less time since they acquired their license. O The older a subject is, the more time since they acquired their license. O This is a mistake. The value should be close to -1. O This is a mistake. The value should be close to 0.
