A team of climbers set up a base camp on a mountain. At noon, two climbers reach an elevation of 300 feet above base camp, and three climbers are below base camp at an elevation of -200 feet. What does 0 represent in the context of this situation?

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
