Goofy Marketing Solutions conducted a survey among 16 randomly selected visitors to the newly opened Outlet Shoppes at Atlanta to measure their satisfaction with the shopping experience. The sample satisfaction score is normally distributed 67with a sample standard deviation of s=7.509. Determine around a mean of x the 95% confidence interval for the population mean from the sample.
