Problem
A pair of devices plays the CHSH game N=2000 times and wins 1640 rounds.
((a)) Using the standard error p(1−p)/N of the measured rate p, from the worked example earlier in this section, find by how many standard errors the result exceeds the classical ceiling 3/4.
((b)) At this same measured rate, find how many rounds would be needed to clear the classical ceiling by 5 standard errors instead.
