WebAug 15, 2024 · Evaluate probabilities α and β. SOLUTION Acceptance region for H 0 is given by { 15; 16; 17; 18; 19; 20 }. α = P (type I error) = P ( x < 15 θ = 0.90) = 0.0114 β = P (type II error) = P ( x ≥ 15 θ = 0.60) = 0.1255 β can be reduced by appropriately changing critical region: If critical region is x < 16 we get α = 0.0433 and β = 0.0509 WebHow is a hypothesis test carried out with the binomial distribution?
