A chemical engineer is investigating the effect of process operating temperature (x) on product yield (y ). The study results in the following data: x 100 110 120 130 140 150 160 170 180 190 y 45 51 54 61 66 70 74 78 85 89 Check if there is any linear relationship between temperature and product yield. If there is, find the equation of the straight line describing the above relation, the correlation coefficient, the total standard deviation and the standard error of estimate...
