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: 1339 1877 2978 3961 5046 7103 7932 7882 8028 8763 8755 8939 9203 x 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 y 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 o². Round your answer to the nearest integer (e.g. 9876). i (b) How does the LTWL size change in average for a year? Round your answer to the nearest integer (e.g. 9876). i (c) Estimate the number of patients in the list in 2014.
