Question 11

Researchers initiated a long-term study of the population of American black bears. One aspect of the study was to develop a model that could be used to predict a bear's weight (since it is not practical to weigh bears in the field). One variable thought to be related to weight is the length of the bear. The accompanying data represent the lengths and weights of 12 American black bears. Total Length (cm) Weight (kg) 135 138 129 120 149 141 140 150 Determine the linear correlation coefficient between the length and weight of the bear. Express your answer as decimal and round your answer to 2 decimal places
