5. Continue with problem 4. (a) Write down the appropriate ANOVA model if we are interested in the group mean of each group, and specify all assumptions this model makes. (b) Estimate the difference in population means for the M group vs. the Y group. (c) Estimate the standard deviation for the difference in sample means between group M and group Y. (d) Assuming the assumptions for ANOVA hold, estimate the probability that an error (e;;) is larger than 2.5. 6. Continue with problem 4. (a) Find the 95% confidence interval for UM - HYTHO 2 (b) Interpret the confidence interval from (a) in terms of the problem. (c) Find the 95% confidence interval for Ho - MY. (d) Interpret your interval from (c) in terms of the prob- lem. (e) Using the results of this problem, which means do you believe are significantly different and why?4.
