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 Complete parts a through d below b Draw a scatter diagram of the data Choose the correct graph below Total Length cm 139 0 135 0 139 0 120 5 149 0 141 0 141 0 150 0 166 0 151 5 129 5 150 0 Weight kg 110 60 90 60 85 100 110 85 155 140 105 110 Critical Values for Correlation Coefficient n 3 0 997 4 0 950 5 0 878 6 0 811 7 0 754 8 0 707 9 0 666 10 0 632 11 0 602 12 0 576 13 0 553 14 0 532 15 0514 16 0 497 17 0 482 18 0 468 19 0 456 20 0 444 21 0 433 22 0 423 23 0 413 24 0 404 25 0 396 26 0 388 27 0381 28 0 374 29 0 367 OA A Weight kg 180 40 100 AM ES 200 Length cm OB Q Q AWeight kg 180 40 100 OTO 200 Length cm Q Q 2 O C AWeight kg 180 40 100 33 200 Length cm Q Q O D ALength cm 180 40 100 200 Weight kg
