function of temperature T(C) and chloride concentration c(g/L). Use multiple linear regression to fit a function that is quadratic in temperature and linear in chloride concentration to these data. In order words, determine the best choices (in a least-squares sense) for the parameters a0,a1,a2,a3 in the expression d=a0+a1T+a2T2+a3c Then use that expression to estimate the concentration of dissolved oxygen for a chloride concentration of 15g/L at T=12C. Compare the result to the actual concentration of 9.09mg/L
