Question

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution.

Test H0 : p1=p2 vs Ha : p1<p2 when the samples have n1=140 with p^1=0.18, and n2=90 with p^2=0.23. 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.
