11.5 For the model described in Problem 11.4, suppose that the variance of U0j

(i.e., τ0 2

) is estimated to be 0.2 and the variance of U1j

(i.e., τ1 2

) is estimated to be 0.1.

a. Interpret these values in the context of this model and variables.

b. How do these variances inform your answers to Problem 11.4?
