I am attempting to find the P-value of a hypothesis test, which compares the success rate of two procedures. A test with 0.05 level of significance is conducted to test the success rate of two procedures.
Procedure A Sample Size: 200, Number of Success: 125
Procedure B Sample Size: 100, Number of Success: 55
The cooprrect p-val in the ans key is 0.2113. Appreciate some guidiance on where Ive gone wrong
