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.
(Round to three decimal places as needed.)
d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
O A. One has 90% confidence that the sample proportion is equal to the population proportion.
O B. There is a 90% chance that the true value of the population proportion will fall between the lower
bound and the upper bound.

d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
O A. One has 90% confidence that the sample proportion is equal to the population propodtion.
O B. There is a 90% chance that the true value of the population proportion will fall between the lower
bound and the upper bound.
O C. 90% of sample proportions will fall between the lower bound and the upper bound.
O D. One has 90% confidence that the interval from the lower bound to the upper bound actually does
contain the true value of the population proportion.
