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 = 986 and x = 522 who said "yes." Use a 99% confidence level.
Click the icon to view a table of z scores.
a) Find the best point estimate of the population proportion p.
(Round to three decimal places as needed.)
b) Identify the value of the margin of error E.
E =
(Round to three decimal places as needed.)
c) Construct the confidence interval.
]<p<]
(Round to three decimal places as needed.)
d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
A. 99% of sample proportions will fall between the lower bound and the upper bound.
B. One has 99% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.
O C. There is a 99% chance that the true value of the population proportion will fall between the lower bound and the upper bound.
O D. One has 99% confidence that the sample proportion is equal to the population proportion.
