Extracted text: Researchers have estimated that office workers in Belgium receive an average of 15 e-mails per day. Assuming this finding to be based on simple random sample of 60 Belgium office workers, with a standard deviation of 3.5 e-mails, construct and interpret the 95% confidence interval for the population mean. Given this confidence interval, would it seem very unusual if another sample of this size were to have a mean of 16.5 e-mails?
