Suppose heights, in inches, of orangutans are normally distributed and have a known population standard deviation of 4 inches and an unknown population mean. A random sample of 16 orangutans is taken and gives a sample mean of 56 inches. Find the confidence interval for the population mean with a 95% confidence level.
