Question : The number of pounds of steam used per month by a chemical plant is thought to be related to the average ambient temperature [in F] for that month .The past year's usage and temperatures are in the following table : 9] Ian . 2 1 185.?9 24 214.47 Mar . 233.93 Apr . 4? 424.84 M ay 5|] 454.58 - Aug. 3'4 6?5.06 Sept . 6 2 562.03 Oct. 952.93 Nov. 359.95 Dec. 223.93 Assuming that a simple linear regression model is appropriate ,t the regression model relating steam usage [y] to the average temperature [X]. What is the estimate of 0'2? What is the estimate of expected steam usage when the average temperature is 55 F? What change in mean steam usage is expected when the monthly average temp erature changes by 1 a F ? Suppose that the monthly average temperature is 4?F. Calculate the fitted value ofy and the corresponding residual
