Question

The necessary conditions having been met, a two-tailed test is being conducted to test the difference between two population proportions. The two sample proportions are  and  , and the standard error of the sampling distribution of   is 0.0085. Under these circumstances, the calculated value of the test statistic will be z = 3.41.

Quizplus · Accepted Answer

The calculated value of the test statistic, z = 3.41, is greater than the critical value for a two-tailed test with a significance level of 0.05 (which is approximately 1.96). Therefore, we can reject the null hypothesis and conclude that there is a significant difference between the two population proportions.
