Question

Refer to the Bulletin of Marine Science (April 2010) study of teams of fishermen fishing for the red spiny lobster in Baja California Sur, Mexico, Exercise. Recall that simple linear regression was used to model y = total catch of lobsters (in kilograms) during the season as a function of x = average percentage of traps allocated per day to exploring areas of unknown catch (called search frequency).
a. Locate and interpret the coefficient of determination, r2, on the SAS printout shown on p. 576.
b. Note that the coefficient of correlation, r, is not shown on the SAS printout. Is there information on the print out to determine whether total catch (y) is negatively linearly related to search frequency (x)? Explain.
