Maria solved the equation -5 x 7/8n = -12 x 1/4. her answer was n = 2 x 4/47. she is fairly confident about her answer, but wants to do a quick check of her solution using estimation. which of the following shows a good check of her answer? -6(2) = -12 -5(-2) = -12 -6(3) = -13 -6(2) = -13

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
