Test H 0 : p 1 = p 2 vs H a : p 1 < p 2 when the samples have n 1 = 170 with p ^ 1 = 0.18 , and n 2 = 90 with p ^ 2 = 0.21 . The standard error of p ^ 1 - p ^ 2 from the randomization distribution is 0.05 . Find the value of the standardized z -test statistic. Round your answer to two decimal places.
