I want to know the answer to the following question:
What percentage of Nobel award winners from the United States in the 20th century have been Ashkenazi Jews?
All the background I'm provided with is that "While they make up about 2% of the U.S. population, 27% of United States Nobel prize winners in the 20th century, a quarter of Fields Medal winners, 25% of ACM Turing Award winners, half the world's chess champions, including 8% of the top 100 world chess players, and a quarter of Westinghouse Science Talent Search winners have Ashkenazi Jewish ancestry.". Is that enough to answer the question?
