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 1464 1894 2815 3803 4708 6654 7532 7415 7671 8376 8285 8645 8922 x 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 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 a". Round your answer to the nearest integer (e.g. 9876). (b) How does the LTWWL size change in average for a year? Round your answer to the nearest integer (eg. 9876). (c) Estimate the number of patients in the list in 2017.
