Question

A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=906 and x=567 who said "yes." Use a 95% confidence level.

a) Find the best point estimate of the population proportion p.

b) Identify the value of the margin of error E.

c) Construct the confidence interval.

d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.

One has

95%

confidence that the sample proportion is equal to the population proportion.

95%

of sample proportions will fall between the lower bound and the upper bound.

There is a

95%

chance that the true value of the population proportion will fall between the lower bound and the upper bound.

One has

95%

confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.
