The department of health studied the number of patients who need liver transplantation. The following data are the Liver Transplantation Waiting List (LTWL), where y is the size (in number of patients) and x is the corresponding year: y 1315 1790 2712 3664 4708 6763 7630 7523 7631 8310 8286 8433 8805 x 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 Round your intermediate answers to four decimal places (e.g. 98.7654). (a) Fit the simple linear regression model using the method of least squares. Find the estimate of o?. Round your answer to the nearest integer (e.g.9876). 62 = (b) How does the LTWL size change in average for a year? Round your answer to the nearest integer (e.g. 9876). ß i (c) Estimate the number of patients in the list in 2016. y = P. (d) Calculate the fitted value of y corresponding to x = 2013. Find the corresponding residual. Round your answer to the nearest integer (e.g.9876). i Round your answer to the nearest integer (e.g. 9876). e =
