The department of health studied the number of patients who need liver transplantation. The following data are the IJver Transplantation Waiting List (LTWL), where y is the size (in number of patients) and x is the corresponding year: Y 1298 1720 2632 3585 4586 6678 7487 7397 7618 8299 8236 8438 8746 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 01:62. Round your answer to the nearest integer (e.g. 9876). #=|:| (b) How does the LTWL size change in average for a year? Round your answer to the nearest integer (e.g. 9876). 131 = Z (c) Estimate the number of patients in the list in 2014. =: (d) Calculate the tted value ofy corresponding to x = 2010. Find the corresponding residual. Round your answer to the nearest integer (63.9. 9876). e: Round your answer to the nearest integer (63.9. 9876). e=l:l
