a) \(\bar{p} \pm \frac{1}{2} \sqrt{\bar{p}(1-\bar{p})/n_i}\)
b) \(\bar{p} \pm \sqrt{\bar{p}(1-\bar{p})/n_i}\)
c) \(\bar{p} \pm 3\sqrt{\bar{p}(1-\bar{p})/n_i}\)
d) \(\bar{p} \pm \sqrt{\bar{p}(1-\bar{p})/n_i}\)
b) \(\bar{p} \pm \sqrt{\bar{p}(1-\bar{p})/n_i}\)
c) \(\bar{p} \pm 3\sqrt{\bar{p}(1-\bar{p})/n_i}\)
d) \(\bar{p} \pm \sqrt{\bar{p}(1-\bar{p})/n_i}\)
