When the necessary conditions are met, a two-tail test is being conducted to test the difference between two population proportions. The two sample proportions are p₁ = 0.25 and p₂ = 0.20 and the standard error of the sampling distribution of $p _ { 1 } - p _ { 2 }$ is 0.04. The calculated value of the test statistic will be: $\begin{array}{|l|l|}\hline A.&z=0.25\\\hline B.&z=1.25\\\hline C.&t=0.25\\\hline D.&t=0.80\\\hline \end{array}$

Question

When the necessary conditions are met, a two-tail test is being conducted to test the difference between two population proportions. The two sample proportions are p₁ = 0.25 and p₂ = 0.20 and the standard error of the sampling distribution of

p _ { 1 } - p _ { 2 }

is 0.04. The calculated value of the test statistic will be:
