Answer

So, the confidence interval $0.222 < p < 0.888$ in the form $\hat{p} \pm E$ is $0.555 \pm 0.333$ .

Steps

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
