A market analyst wants to estimate the average spending per day in a population. A random sample of n=400 is taken and the sample mean is found to be $500. Suppose we know that the population standard deviation of spending is o=$100. Provide a 95% confidence interval estimate of the population mean. What is the value of the margin of error?
