Question
The basic principle of the IPPS payment system is that the ‘levels’ (no CC/CC/MCC) of a MS-DRG family has different resource intensity and therefore should be paid differently. Use the CHF data to test this hypothesis. Use charge as a measure of resource intensity. Be sure to state the null and alternative hypotheses and set the alpha prior to performing the test.
Can you conclude which MS-DRGs have significantly different average charges?

Null Hypothesis: There is no significant different in the average charges of MS-DRGs.

Here the Pvalue=0.000 indicates the rejection of the null hypothesis at 5% level of significance.
Hence MS-DRGs have significantly different average charges.
