In the Sign Test Applications, the Normal Approximation to the Binomial

Short Answer

In the sign test applications, the normal approximation to the binomial distribution may be used whenever the number of nonzero differences is greater than or equal to: $\begin{array}{|l|l|}\hline\text { A. } & 5 \\\hline \text { B. } & 20 \\\hline \text { C. } & 10 \\\hline \text { D. } & 30 \\\hline\end{array}$
