What is the best estimate of s2, the variance of therandom error ?b. Do the data indicate that texture and storage temperatureare linearly related? Use a .05.c. Calculate the coefficient of determination,r2.d. Of what value is the linear model in increasingthe accuracy of prediction as compared to thepredictor, y?
