Consider a largesample level 001 test for testing H0 p 02 a

Consider a large-sample level 0.01 test for testing H0: p = 0.2 against H a : p > 0.2. For the alternative value p = 0.21, compute Beta (0.21) for sample sizes n = 121, 1600, 10,000, 40,000, and 90,000. (Round your answers to four decimal places.) For Beta = x/n = 0.21, compute the P-value when n = 121, 1600, 10,000, and 40,000. (Round your answers to four decimal places.)
