OHIP records show the average length of stay in Ontario hospitals is 5.4 days. A researcher sampled 125 patient records at US hospitals and found that the mean stay was 4.6 days, with a standard deviation of 1.1 days. Does the data support the idea that Ontario health insurance practices lengthen the stay in Canadian hospitals? (alpha = 0.05)
