Refer to the Bulletin of Marine Science (Apr. 2010) study of teams of fishermen fishing for the red spiny lobster in Baja California Sur, Mexico, Exercise 11.63 (p. 614). 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. 614.
b. Note that the coefficient of correlation, r, is not shown on the SAS printout. Is there information on the printout to determine whether total catch (y) is negatively linearly related to search frequency (x)? Explain.
