6. It is known that the tensile strength of a plastic increases as a function of the time it is heat treated. The following data are collected: Time 10 15 20 25 40 50 55 60 75 Tensile strength 5 20 18 40 33 54 70 60 78 (a) Fit a straight line to these data and use the equation to determine the tensile strength at a time of 32min. (b) Determine the coefficient of determination, standard deviation and the standard error of estimate.
