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 1216 1702 2716 3707 4706 6760 7631 7552 7675 8444 8390 8554 8795 x 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 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). 6 = i (b) How does the LTWL size change in average for a year? Round your answer to the nearest integer (e.g. 9876). P = 1 (c) Estimate the number of patients in the list in 2017. (d) Calculate the fitted value of y corresponding to x = 2014. Find the corresponding residual. Round your answer to the nearest integer (e.g. 9876). ŷ = i Round your answer to the nearest integer (e.g. 9876). e = i
