Using the given values m = 80 and n = 80, along with the values previously calculated, p, = 0.575, p, = 0.2, p = 0.3875, and q = 0.6125, calculate the test statistic z, rounding the result to two decimal places. p1 - P 2 Z = Vpa( 1 + 1 0.575 - 0 V0.3875(0.6125)( 1 + 80 Because we are testing Ha: P, - p, # 0, we have a two-tailed test. Recall that the P-value for a two-tailed test is 2 . (Area under the standard normal curve to the right of (z|), or 2[1 - @(|z1)]. Use the value of z calculated above and refer to the table of standard normal curve areas to calculate the P-value rounded to four decimal places. P-value = 2[1 - @(1z1)] = 2 1 - 0[ =
