You obtain 42.8% successes in a sample of size n1=621n1=621 from
the first population. You obtain 37.7% successes in a sample of
size n2=355n2=355 from the second population. For this test, you
should NOT use the continuity correction, and you should use the
normal distribution as an approximation for the binomial
distribution.
What is the test statistic for this sample? (Report answer accurate
