Explanation / Answer

The statistical software output for this problem is:

One sample proportion summary confidence interval:
p : Proportion of successes
Method: Standard-Wald

99% confidence interval results:

Hence,

a) Best point estimate = 0.523

b) Margin of error = (0.56240087 - 0.48443108)/2 = 0.039

c) Confidence interval: (0.484, 0.562)

d) We are 99% confident that the true population proportion of respondents who felt vulnerable in identity theft will lie between 0.484 and 0.562.
