The high price of medicines is a source of major expense for those seniors in the United States who have to pay for these medicines themselves. A random sample of 1600 seniors who pay for their medicines showed that they spent an average of $4300 last year on medicines with a standard deviation of $500. Make a 90% confidence interval for the corresponding population mean. Round your answers to cents. i to $ i %24
