a) \(z_i=\frac{n\hat{p}_i+n\bar{p}}{\sqrt{n\bar{p}(1+\bar{p})}}\)
b) \(z_i=\frac{n\hat{p}_i-n\bar{p}}{\sqrt{n\bar{p}(1+\bar{p})}}\)
c) \(z_i=\frac{n\hat{p}_i+n\bar{p}}{\sqrt{n\bar{p}(1-\bar{p})}}\)
d) \(z_i=\frac{n\hat{p}_i-n\bar{p}}{\sqrt{n\bar{p}(1-\bar{p})}}\)
b) \(z_i=\frac{n\hat{p}_i-n\bar{p}}{\sqrt{n\bar{p}(1+\bar{p})}}\)
c) \(z_i=\frac{n\hat{p}_i+n\bar{p}}{\sqrt{n\bar{p}(1-\bar{p})}}\)
d) \(z_i=\frac{n\hat{p}_i-n\bar{p}}{\sqrt{n\bar{p}(1-\bar{p})}}\)
