I’m using JMP Pro 12.1 and have questions that I hope you could help on using JMP to answer them. Product runs are generating defects. Mean defect rate = 0.002 (average 1 defect every 500pcs) Std Dev = 0.01 1. What is the probability of finding at least 1 defect when I random sample 500pcs? 2. What is the minimum sample size I need to sample in order to get at least 1 defect at Alpha = 0.05 3. Is Alpha = 0.05 equivalent to 95% Confidence Interval?
