The confidence interval is given by
ME
The Lower Limit = 69.1 - 2.5 = 66.6
The Upper Limit = 69.1 + 2.5 = 71.6
The Confidence interval is 66.6 to 71.6

a.) The margin of error in a 95% confidence interval for the true mean of a population is 2.5, based on a random sample of 100 measurements. If the sample mean is 27.5, the 95% confidence interval must be b.) In a random sample of 100 measurements from a population with known standard deviation 200, the average was found to be 50. A 95% confidence interval for the true mean is c.) A.C. Neilsen reported that children between the ages...
