Please answer this, briefly explain. Use R code if necessary. Thanks!

Imagine that a one way, fixed-effects ANOVA model holds. Specifically, suppose that, under the conditions of the experiment, unbeknownst to the experimenters, and with treatment 1 as the baseline, A = 17, 72 = 9, 73 = 5, T4 = 13, and of = 2. Which of the treatments has the largest expected value? For a factor effects parameterization with treatment 4 as baseline, what values would the parameters take
