What is the confidence interval?

Question Help Assume that population mean is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interv Sample size, n =64; sample mean, x =74.0 cm; sample standard deviation, s =5.0 cm The margin of error is 1.2 cm. (Round to one decimal place as needed.) Find the 95% confidence interval. cm
