Problem
Express the confidence interval $0.222
Solution
Step 1 ：The confidence interval is given by the range $0.222
Step 2 ：To find $\hat{p}$, we can calculate the average of the lower and upper bounds of the interval. $\hat{p} = \frac{0.222 + 0.888}{2} = 0.555$
Step 3 ：To find $E$, we can subtract the lower bound from $\hat{p}$. $E = 0.555 - 0.222 = 0.333$
Step 4 ：So, the confidence interval $0.222
