Question

Wind turbine blade stress. Refer to the Wind Engineering (Jan. 2004) study of two types of timber-radiata pine and hoop pine-used in high-efficiency small wind turbine blades, presented in Exercise. Data on stress (y) and the natural logarithm of the number of blade cycles (x) for each type of timber were analyzed by means of simple linear regression. The results are as follows, with additional information on the coefficient of determination:
Interpret the value of r2 for each type of timber.
