Answer:
The confidence interval is (0.444 ± 0.111).
Step-by-step explanation:
The general form of a confidence interval for single proportion is: 
The interval provided is: (0.333 < p < 0.555)
Then

Solving the two equation simultaneously:
Add (i) and (ii),

Substitute the value of
in (i) to compute the value of <em>E:</em>

Thus, the confidence interval is,
