Hi, I need help with one-sample z proportions and two sample z for proportions

One-sample Z-Test for Proportions

1.Calculate the mortality rate for the sample of patients discharged with MS-DRG 291 (42%)

2.Determine the mortality rate for MS-DRG 291 for Medicare patients in 2011 from the HCUP website. (5.80%)

3.Test the hypothesis that the mortality rate for the hospital that generated the sample data is different from the US rate.

4.Select an appropriate alpha level.

Two-sample Z-test for Proportions

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

(I will need to attach the excel spreadsheet with the data.)
