A physics experiment consists of recording paired data consisting of the time (seconds) elapsed since the beginning of the experiment and the distance (cm) of a robot from its point of origin. Using the paired time/distance data, the value of r is calculated to be 0. Is it correct to conclude that there is no relationship between time and distance? Explain.
