A manufacturer receives parts from two suppliers. An SRS of 400 parts from supplier 1 fınds 20 defective. An SRS of 100 parts from supplier 2 fınds 10 defective. Let p1 and p2 be the proportion of all parts from suppliers 1 and 2, respectively, that are defective. Find a 95% confidence interval for p1 - p2. Finally, provide the numerical value of the Upper Confidence Interval (UCL). Round your final answer to 4 decimal places.
