Construct an example and show the solution of constructing a confidence interval, where the normal distribution (z-scores) or t-distribution would be used to estimate the population mean with confidence c = 90%, 95% or 99% (pick one). Please explain why you'd use a z or t-distribution. Make sure to show how you obtain E (use the appropriate formula). Interpret the results
