Costs are rising for all kinds of medical care. The mean monthly rent at assisted-livingfacilities was reported to have increased 17% over the last five years to $3486 (theWall Street Journal, October 27, 2012). Assume this cost estimate is based on a sampleof 120 facilities and, from past studies, it can be assumed that the population standarddeviation is s = $650.a. Develop a 90% confidence interval estimate of the population mean monthly rent.b. Develop a 95% confidence interval estimate of the population mean monthly rent.c. Develop a 99% confidence interval estimate of the population mean monthly rent
