Sockett et al. (1987) report data related to patterns of residual insulin secretion in children. A portion of the study was concerned with whether age can be used to predict the logarithm of C-peptide concentrations at diagnosis. The observed values are Age (X): 5.2 8.8 10.5 10.6 10.4 1.8 12.7 15.6 5.8 1.9 2.2 4.8 7.9 5.2 0.9 11.8 7.9 1.5 10.6 8.5 11.1 12.8 11.3 1.0 14.5 11.9 8.1 13.8 15.5 9.8 11.0 12.4 11.1 5.1 4.8 4.2 6.9 13.2 9.9 12.5 13.2 8.9 10.8 C-peptide (Y): 4.8 4.1 5.2 5.5 5.0 3.4 3.4 4.9 5.6 3.7 3.9 4.5 4.8 4.9 3.0 4.6 4.8 5.5 4.5 5.3 4.7 6.6 5.1 3.9 5.7 5.1 5.2 3.7 4.9 4.8 4.4 5.2 5.1 4.6 3.9 5.1 5.1 6.0 4.9 4.1 4.6 4.9 5.1 Create a scatterplot for these data and consider whether a linear rule for predicting Y with X is reasonable.
