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 99% confidence interval for p given that p = 0.7 and n = 100. Round your answer for the point estimate to two decimal places, and your answers for the margin of error and the confidence interval to...
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 99% confidence interval for p given that p^=0.75 and n=140. Round your answer for the point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places. Point...

Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 19, upper bound is 27. The point estimate of the population mean is _______ . The margin of error for the confidence interval is _______ .
An economist would like to estimate the 99% confidence interval for the average real estate taxes collected by a small town in California. In a prior analysis, the standard deviation of real estate taxes was reported as $1,520. [You may find it useful to reference the z table.] What is the minimum sample size required by the economist if he wants to restrict the margin of error to $660? (Round intermediate calculations to at least 4 decimal places and "z"...
