Let a = and b = . determine if the equation ax = b is consistent for all possible b1, b2, b3. if the equation is not consistent for all possible b1, b2, b3, give a description of the set of all b for which the equation is consistent (i. e., a condition which must be satisfied by b1, b2, b3 ).

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
