A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a standard deviation of 54 minutes with a mean life of 828 minutes. If the claim is true, in a sample of 107 batteries, what is the probability that the mean battery life would differ from the population mean by more than 8.3 minutes? Round your answer to four decimal places.

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
