Because we are testing H₂: P₁ P₂ # 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 Iz]), or 2[1 - (|z|)].
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.
