A factory produces screws. A screw has a probability of 0.01 to be defective. Screws are packed 10 per package. The company returns the customer’s money if more than 1 from 10 screws are defective in the package. What is the probability that the package bought by the customer will contain more than 1 defective screw?

    3. A factory produces screws in batches of 100,000. The probability that a screw is defective is 0.01%. Assume that defects occur independently of each other. (a) Approximate the probability that 15 or more screws in a batch are defective using the normal approximation to the binomial distribution. (b) Approximate the probability that 3 or fewer screws in a batch are defective using the normal approximation to the binomial distribution. (c) Approximate the probability that 3 or fewer screws in...

    I. A factory produces a type of micro chip with defective rate 0.5%. The chips are packaged as set of 10. Each set is considered as returnable if it contains more than 1 defective chips. (a) (10 points) What is the probability that a randomly chosen set is returnable? (b) (10 points) If a customer buys 10000 sets, approximate the probability that he will return more than 5 sets?

  • A machining process produces screws for which the population proportion of screws with defective threads is...

    A machining process produces screws for which the population proportion of screws with defective threads is .10 (10%). A new laser-enhanced process has become available and the developer claims that the population proportion of screws with defective threads will be less than .10. To test the validity of this claim, 900 screws produced by the new process are selected at random and the sample proportion of defectives is computed. This result will be used to make a decision as to...

    Suppose machine 1 produces items that are independently defective with probability 0.01, machine 2 produces items that are independently defective with probability 0.02, and machine 3 produces items that are independently defective with probability 0.04. Suppose we purchase a box with 100 items in it, all of which were produced by the same machine. The box was produced by machine 1 with probability 0.5, by machine 2 with probability 0.3, and by machine 3 with probability 0.2. (a) Find the...

    1) Three dice are rolled. If each lands on a different number, find the probability that one is 3? 2) ) Three machines (A, B, C) manufacture screws. They manufacture 25%, 35%, and 40% of the screws, respectively. The output screws are defective at 2%, 3%, and 5%, respectively. If you choose a random screw produced at the factory and it is defective, what is the probability it came from each machine A, B, and C
