Comparing failure rates between two processes
Process A has 2 fails out of 1000 units and Process B has 4 fails out of 750 units. Point estimates of failure rate are 2/1000 = 0.002 and 4/750 = 0.005 for Process A and B, respectively. How can I use JMP to prove statistical significance of failure rate difference? How do I setup the data table for that? How to put confidence interval around those failure rate estimates to check if intervals are...
