![Use the sample data and confidence level given below to complete parts (a) through (d).
A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, \( n = 1065 \) and \( x = 565 \) who said "yes." Use a 95% confidence level.
a) Find the best point estimate of the population proportion \( p \).
\[
\text{(Round to three decimal places as needed.)}
\]
b) Identify the value of the margin of error \( E \).
\[ E = \]
\[
\text{(Round to three decimal places as needed.)}
\]
c) Construct the confidence interval.
\[
< p <
\]
\[
\text{(Round to three decimal places as needed.)}

Step 1
From the provided information,
Sample size (n) = 1065, x = 565
a)
The best point estimate of the population proportion is sample proportion.
Thus, the required sample proportion can be obtained as:
Step 2
b)
Confidence level = 95%
The z value at 95% confidence level from the standard normal table is 1.96.
The required margin of error can be obtained as:
