Two researchers conduct separate studies to test Ho: p=0.50 against H₁: p0.50, each with n=400. Researcher A gets 219 observations in the category of interest, and p=219/400 =0.5475. Researcher B gets 221 in the category of interest, and p=221/400=0.5525. Complete parts (a) through (e) below. a. Determine the P-value for Researcher A. The z test statistic is 1.90. The P-value is.
