The table below shows data collected on the length and weight of sand sharks. Length 60 62 64 66 68 70 72 Weight 105 114 124 131 139 149 158 A linear regression analysis is run on this data and results in a linear regression equation of y = 4.36x - 156.14 where x is the length of the shark in inches and y is the weight of the sharks in pounds. The correlation coefficient (r) is calculated as 0.9991. Calculate the r-squared value and interpret it in context. A. 99.95% of the variation in a sand shark's weight can be explained by its length. B. 99.82% of sharks fit our model. C. 99.82% of the variation in a sand shark's weight can be explained by its length. D. 99.95% of sharks fit our model.
