Smart phone: Among 251 cell phone owners aged \( 18-24 \) surveyed, 109 said their phone was an Android phone. Part 1 of 3 (a) Find a point estimate for the proportion of cell phone owners aged 18 - 24 who have an Android phone. Round the answer to at least three decimal places. The point estimate for the proportion of cell phone owners aged \( 18-24 \) who have an Android phone is 0.434 . Part: \( \mathbf{1} / \mathbf{3} \quad \) Part 2 of 3 (b) Construct a \( 99.8 \% \) confidence interval for the proportion of cell phone owners aged \( 18-24 \) who have an Android phone. Round the answers to at least three decimal places. A \( 99.8 \% \) confidence interval for the proportion of cell phone owners aged \( 18-24 \) who have an Android phone is \( \square<p<\square \).
