Answer to relevant QuestionsH0: p = 0.3 versus H1: p > 0.3 n = 200; x = 75; α = 0.05 Test the hypothesis using (a) The classical approach and (b) The P-value approach. Be sure to verify the requirements of the test. H0: p = 0.4 versus H1: p ≠ 0.4 n = 1000; x = 420; α = 0.01 Test the hypothesis using (a) The classical approach and (b) The P-value approach.
