Calculate a margin of error given a confidence interval Question In a questionnaire, a random sample of commuters were asked whether it takes them more than 30 minutes to commute to work in the morning. The resulting confidence interval for the proportion of commuters who drive more than 30 minutes to work in the morning is is (0.27,0.51) What is the sample proportion, p?

What is the margin of error for this confidence interval: (0.28, 0.32)
Use the given confidence interval to find the margin of error and the sample proportion. (0.783,0.807)
what is the margin of error and the confidence interval? Question Help In a random sample of seven people, the mean driving distance to work was 24.7 miles and the standard deviation was 6.6 miles. Assuming the population is normally distributed and using the I-distribution, a 90% confidence interval for the population mean is (15.5, 33.9) (and the margin of error is 9.2). Through research, it has been found that the population standard deviation of driving distances to work is...
Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...
Use the given confidence interval to find the margin of error and the sample mean. (14.6,23.8)
Use the given confidence interval to find the margin of error and the sample proportion. (0.630,0.658) E(Type an integer or a decimal.) (Type an integer or a decimal.)
To calculate a confidence interval, the margin of error (E) must first be calculated. The Margin of Error, E, for means is: E = 1.96*s/sqrt(n), where s is the sample standard deviation, n is the sample size. The “sqrt” stands for square root. The Margin of Error, E, for proportions is: E = 1.96*sqrt[p*(1-p)/n], where s is the sample standard deviation, n is the sample size, and p is the proportion. Use the Confidence Interval formula above, and the correct...
