A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures. Historically, the failure rate for LED light bulbs that the company manufactures is 11%. Suppose a random sample of 10% LED light bulbs is selected. a. What is the probability that none of the LED light bulbs are defective? b. What is the probability that exactly 1 of the LED light bulbs is defective? c. What is the probability that 3 or fewer of...
A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures.

A shipment of 50,000 transistors arrives at a manufacturer plant. The quality control engineer at the plant obtains a random sample of 500 transistors and will reject the entire shipment if 10 or more of the resistors are defective. Suppose that 4% of the resistors in the whole shipment are defective. Describe the sampling distribution of the sample proportion of defective resistors, Justify your answer. What is the probability the engineer accepts the shipment? Do you believe the acceptance policy...

(a) What is the probability that for a single store exactly 5 customer complaints are received in a given week? (b) What is the probability that for a single store at least 3 customer complaints are received in a given week? (c) What is the probability that for a single store no more than 3 customer complaints are received...
Company records show that the proportion of defective parts has historically been 5%, however a quality control engineer believes that due to budget cuts these numbers have increased. To test this claim a random sample of N = 15 parts will be taken and if more than two defective parts are found the inspector will conclude that the proportion of defective parts has increases. If the true probability of a defective part is in fact p = 10% what is...
1. 2. 3. A company makes auto batteries. They claim that 81% 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 70 such batteries that are good for 70 months or more. a. What is the probability that this sample proportion is within 0.02 of the population proportion? Round your answer to two decimal places b. What is the probability that this...
