If A = {0, 1, 2, 3, 4, 5} , B = {2, 4, 6 } ,find i) AUB ii) A ∩ B iii) A – B iv) B – A , Also verify that

a) n(A – B) = n(AUB) – n(B) = n(A) – n( A ∩ B )
b) n(AUB) = n(A – B) + n(B – A) + n( A ∩ B )

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
