Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. Round your final answers to 3 decimal places. n = 130, x = 69; 90% confidence You will need to calculate the margin of error, followed by the lower and upper end of the confidence interval. Margin of Error: choose your answer.. Confidence Interval: choose your answer.
