Alligator Length (inches) (x) Weight (pounds) (y)

112 666

97 617

104 532

92 481

118 674

109 601

90 538

73 506

103 607

127 804

Calculate the correlation coefficient. Round to three decimals.

r =

Find the equation of the regression line. Round each value to two decimals.

NOTE: Please be careful with your rounding here, if you round improperly in your line equation, it is possible to get the line correct, but then the prediction incorrect.
