DS 12.11.6 contains the circumferential strains 5 and lesion areas L of n = 12 specimens of human arteries with atherosclerosis. This disease is commonly referred to as ''hardening of the arteries"" due to the accumulation of plaque on the artery walls. The lesion area measures the amount of plaque that has accumulated on the artery walls and can be thought of as the disease severity. The circumferential strain is a measure of the deformability of the artery tissue. A model that relates the circumferential strain S to the lesion area L is helpful in assessing the potential impact of various levels of atherosclerosis.
(b) After a suitable transformation of the variables, find point estimates for γ0 and γ1.
(c) Calculate two-sided 95% confidence intervals for γ0 and γ1.
(d) What is the predicted circumferential strain of an artery with a lesion area of 10.0 mm2?
