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. Click the icon to view the data table. Click the icon to view the critical values table. ..... (a) Which variable is the explanatory variable based on the goals of the research? O A. The number of bears B. The weight of the bear O C. The length of the bear (b) Draw a scatter diagram of the data. Choose the correct graph below. O A. O B. O C. D.

You've heard of "Florida Man;" now meet "Florida Bear." This problem involves data from a subspecies of black bear found in Florida, Ursus americanus floridanus. The data were collected by T. D. Bartareau as part of a study published in the Journal of Fish and Wildlife Management (2017, vol 8, pp 234- 239). Before you begin consult the info sheet included at the end (a) Do you predict an allometric or isometric scaling relationship between body weight and body length? Explain. (b) Based on your answer to part a, what would a plot of log body weight (vertical axis) versus log body length (horizontal axis) look like? (c) Using the data provided, create a plot of log body weight versus log body length. Make sure to label the axes. Why might someone think your plot fails to provide clear support for your claim in part b? (d) Using the tools described on the info sheet to isolate portions of the dataset, refine your use of data in part c to strengthen support for your claim in b. Why does…
