The answer cannot be determined from the given information.When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight?O A. No, it is easier to measure weight than chest size because the chest is not a flat surface.O B. Yes, it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale. The chest size could be used to predict weight because there is a linear correlationbetween the two.O C.

The chest size could not be used to predict weight because there is not a linear correlationbetween the two.O D. Yes, it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale.

ab! ourses The accompanying technology output was obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of a sample of 40 people. Along with the paired sample data, the technology was also given a foot length of 13.6 cm to be used for predicting height. The technology found that there is a linear correlation between height and foot length. If someone has a foot length of 13.6 cm, what is the single value that is the best predicted height for that person?
