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.

Use the confidence interval to find the estimated margin of error. Then find the sample mean.   A store manager reports a confidence interval of (48.1,78.7) when estimating the mean price​ (in dollars) for the population of textbooks. The estimated margin of error is?

Use the formula in this example to determine the sample size, n.The estimated prevalence is 19%, and the desired confidence level is 93% with a margin of error of 4%. (Round your answer to the nearest integer.)n =

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=931 and x=548 who said​ "yes." Use a 99% confidence level. LOADING... Click the icon to view a table of z scores.   ​b) Identify the value of the margin of error E.
