Chapter 07, Section 7.6, Problem 065 Brooklyn Corporation manufactures DVDS. The machine that is used to make these DVDS is known to produce 6% defective DVDS. The quality control inspector selects a sample of 100 DVDS every week and inspects them for being good or defective. If 10% or more of the DVDS in the sample are defective, the process is stopped and the machine to readjust the machine? readjusted. What is the probability that based on a sample of 100 DVDS the process will be stopped Round your answer to four decimal places. the absolute tolerance is +/-0.0035 Chapter 07, Section 7.6, Problem 066ab A company makes auto batteries. They claim that 85% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p be the proportion in a random sample of 60 such batteries that are good for 70 months or more. a. What is the probability that this sample proportion is within 0.04 of the population proportion? Round your answer to two decimal places. b. What is the probability that this sample proportion is less than the population proportion by 0.06 or more? Round your answer to two decimal places.
