Question 12

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 82 138 84 129 70 120 67 149 92 141 90 140 89 150 98 Write the regression equation (round your final answer to 2 decimal places). Express your answer in the form: y - a + bx O y = 1.05x - 59.83 O y = -59 - 1.04x O y=-59.83+1.04x
