b. Calculate 95% confidence interval estimates of $\mu_1 - \mu_2$, $\mu_1 - \mu_3$, and $\mu_2 - \mu_3$ with Tukey's HSD approach. (If the exact value for $\pi_T - c$ is not found in the table, then round down. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)
