Consider the one-way ANOVA model whereyij = μ+αi +εijwhere εij ∼ N(0,σ ) for i = 1,…,I and j = 1,…,J.iid 2(a) Derive the MLEs of μ, αi, i = 1,…,I, and σ2.(b) What are the MLEs of μ and σ2 under the null hypothesis: H0 : α1 =α2 =…=αI =0? 2. Problem 13.18 from J. Rice “Mathematical statistics and data analysis” page 536.3. In professional basketball games during 1980-1982, when Larry Bird of the Boston Celtics shot a pair of free throws, 5 times he missed both, 251 times he made both, 34 times he made only the first, and 48 times he made only the second.
