When bears were anesthetized, researchers measured the distance (in inches) around their chests and they weigher the bears (inpounds). Based on the results, does a bear's weight seem to be related to its chest size? Do the results change if the chest measurements are converted to feet? ( you need to determine r)
X Chest (in.), Y Weight (lb.) (X,Y) 26,90; 45,344; 54,416; 49,348; 41,262; 49,360; 44,332; 19,34
Is there a linear corielation? How strong? Positive or Negitive correlated? Predict the weight of a bear whose chest measures 30 in.?
