1.A bank has 820 accounts. The manager took a random sample of 60 of these accounts. The sample mean was $127.43, and the sample standard deviation was $43.27. Find a 90% confidence interval for the population mean and a 95% confidence interval for the total amount of these accounts. (Note: you are given the population size N from which we are sampling; so this is finite sample problem.)
