Help #2: percentage of billed charges that are actual costs

[anthony1954]

A state health web site provides information on the cost-to-charge ratio (the percentage of billed charges that are actual costs to the hospital). The cost-to-charge ratios for both inpatient and outpatient care in 2002 for a sample of six hospitals of that state follow. (Use a statistical computer package to calculate the P-value. Use μ_inpatient − μ_outpatient. Round your test statistic to two decimal places and your P-value to three decimal places.)

Hospital	2002 Inpatient Ratio	2002 Outpatient Ratio
1	85	68
2	103	66
3	89	64
4	78	75
5	76	53
6	76	52
