Perform a hypothesis test to determine if the mortality rate for MS-DRG 292 and MS-DRG 293 are statistically different.

DRG 292= N 144 mortality percent is 2.1%

DRG 293= N 81 mortality percent is 2.5%

Follow the Six Steps of Hypothesis Testing to conduct the test.

1.State the Null Hypothesis:

2.Set the Alpha Value:

3.Perform the calculations in Excel to calculate the Z statistic, and report it here:

4.Determine the critical value, and report it here:

5.Decide to accept or reject the null hypothesis.State your decision here and your rationale for doing so:

6.Interpret the results (narrative form, related to the business problem, as if you were reporting the results to leadership) here:
