Independent random samples of 140 observations were randomly selected from binomial populations 1 and 2, respectively. Sample 1 had 82 successes, and sample 2 had 87 successes.
Suppose that, for practical reasons, you know that
p1
cannot be larger than
p2.
Test the appropriate hypothesis using α = 0.10.
Find the test statistic. (Round your answer to two decimal places.)
z =
