\[
(\ \_\_\_\_ ,\ \_\_\_\_ \ )
\]

b. Construct a 90% confidence interval for \( p \) assuming \( n = 550 \).

\[
(\ \_\_\_\_ ,\ \_\_\_\_ \ )
\]

c. Make a 90% confidence interval for \( p \) assuming \( n = 1275 \).

\[
(\ \_\_\_\_ ,\ \_\_\_\_ \ )
\]

d. Does the width of the confidence intervals constructed in parts a through c decrease as the sample size increases?
