Answer 1

Solution :

Point estimate ($\hat p$) = (Lower confidence interval + Upper confidence interval) / 2

                            = (0.111 + 0.333) / 2

                            = 0.222

Margin of error (E) = Upper confidence interval - $\hat p$

                           = 0.333 - 0.222

                           = 0.111‬

In the form of :

$\hat p$ - E < p < $\hat p$ + E is,

0.222 - 0.111 < p < 0.222 + 0.111
