A Sample of Size 125 Selected from One Population Has $\begin{array}{|l|l|}\hline A&\text {-0.060 }\\\hline B&\text {-0.977 }\\\hline C&\text { -0.940}\\\hline D&\text {-0.472 }\\\hline\end{array}$

Short Answer

A sample of size 125 selected from one population has 55 successes, and a sample of size 140 selected from a second population has 70 successes. The test statistic for testing the equality of the population proportions is equal to: $\begin{array}{|l|l|}\hline A&\text {-0.060 }\\\hline B&\text {-0.977 }\\\hline C&\text { -0.940}\\\hline D&\text {-0.472 }\\\hline\end{array}$
