Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p= 0.84 versus H,: p#0.84 n= 500, x= 410, a = 0.01 Is npo (1-Po) 2 10? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. Yes, because npo (1-Po) = O B. No, because npo (1-Po) =
