4.) A simple random sample of size n is drawn from a population that is normally distributed. Using the data, it was found to be: x-bar = 108, and s = 10. Construct a 95% confidence interval about μ if the sample size is 25. Construct a 95% confidence interval about μ if the sample size is 10. Compare your results from Parts (a) and (b). How does decreasing the sample size affect the margin of error? Construct a 90% confidence interval about μ if the sample size is 25.
