Curtis and Kim have been given the same two-variable data about the weights of 250 dolphins in captivity and the amount of fish each one eats daily (in pounds). Kim uses a quadratic model in projecting how much captive dolphins eat daily. This model has a coefficient of determination of 0.8766. Curtis uses a linear model in projecting how much the dolphins eat. This model has a coefficient of determination of 0.84775. Whose model fits the dolphin data best? Explain why.
