Using the correlations between the first eight statements of the previous exercise, fit a correlated two-factor model in which statements 1, 3, 4, and 8 are assumed to be indicators of a latent variable, doctor’s responsibility, and statements 2, 5, 6, and 7 are assumed to be indicators of a latent variable, patient’s responsibility. Find a 95% confidence interval for the correlation between the two latent variables.
