(c) Calculate the values of the residuals from the least squares line for the four observations for which temperature is 186. Why do they not all have the same sign? The four observations for which temperature is 186, written as ordered pairs, are: (186, 0.89), (186, 1.86), (186, 2.03), and (186, 2.69). Recall the residual from the least squares line is the difference between the observed and predicted values. In part (b), we calculated the predicted value for a tank temperature of 186 to be 1.9057. Use this value to calculate the residuals for each of the four observations, rounded to two decimal places. (186, 0.89): 0.89 1.9057 -1.02 (186, 1.86): 1.86 1.9057 -0.05 (186, 2.03): 2.03 - 1.9057 = (186, 2.69): 2.69 -1.9057 = These residuals do not all have the same sign because in the first two observations listed, the observed efficiency ratios were ---Select-- For the third and fourth observations, the observed efficiency ratios were ---Select--than the predicted value, resulting in ---Select--- Submit Skip (you cannot come back) than the predicted value, resulting in ---Select--- residuals. residuals.
