Health insurers and the federal government are both putting pressure on hospitals to shorten
the average length of stay (LOS) of their patients. In 2016, the average LOS for non-heart
patients was 4.6 days. A random sample of 20 hospitals in one state had a mean LOS for
non-heart patients in 2000 of 3.8 days and a standard deviation of 1.2 days. Calculate
the 95 and 90 percent confidence intervals for the population mean LOS for non-heart patients in these
hospitals in 2010. Briefly compare and discuss.
