Construct a confidence interval for a population mean. In order to estimate the number of 911 calls at the emergency operations center (EOC) in Pineville, volunteers randomly contacted 40 similar EOCs around the nation. They learned that the Mean is 42.0 calls per month and that the Standard Dev is 6.5 calls per month. Construct a 95% confidence interval of the mean calls at the EOCs per month.
