(Round will numerical values to four decimal places.) Y- (b) Calculate point estimate for true average efficiency ratio when tank temperature is 18). (Round your answer to four decimal places.) (c) Calculate the values of the residuals from the least squares line for the four observations for which temperature is 183. (Round your answers to two decimal places (183, 0.80) (183, 1.71) (183, 1.98) (183, 264) Why do they not all have the same sign?
