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 interval. Sample size, n= 100; sample mean, x = 74.00 cm; sample standard deviation, s=5.00 cm The margin of error is cm. (Round to two decimal places as needed.) Find the 95% confidence interval. cm<u< cm (Round to two decimal places as needed.)
