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