A machine that manufactures automobile parts produces defective parts 13% of the time. If 10 parts produced by this machine are randomly selected, what is the probability that at least 2 of the parts are defective? Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.

A machine that creates paper straws will occasionally make a straw that is too short. This happens with probability 0.07. Let X = the number of paper straws that are too short in a randomly selected box of 16 straws. If based on the total weight of the box you know that at least one straw is too short, what is the probability that exactly one straw is too short?

2. You need to make 7 usable experimental prototypes for a part that is rather difficult to fabricate effectively. On any attempt to make the part there is a 0.8 probability that the process will turn out successful and the part will be usable. a.) What is the probability that it will take you 10 attempts to end up with 7 usable parts? b.) What is the expected number of attempts you must make and what is the standard deviation?...

Problem 3 A manufacturer has four classifications (A, E, LL, and V) for its components. A batch of 100 components is expected to be populated with 45, 25, 4, and 26 of components A, E, LL, and V, respectively. The company is interested in carrying out quality control measures on their products by randomly sampling a certain number of products from each batch. What is the smallest sample size that can be used by the manufacturer to...

In a particular manufacturing plant, two machines (A and B) produce a particular part. One machine (B) is newer and faster. In one five-minute period, a lot consisting of 32 parts is produced. Twenty-two are produced by machine B and the rest by machine A. Suppose an inspector randomly samples fourteen of the parts from this lot. What is the probability that exactly two parts were produced by machine A? What is the probability that half of the parts were...

Each time a machine fills a can, it under-fills it with probability 0.08. Let X = the number of cans that are under-filled in a randomly selected box of 12 cans. If based on the total weight of the box you know that at least one can is under-filled, what is the probability exactly one is under-filled?

suppose that our concern is with an inspection process where the objective is to inspect machine parts let Ai denote the event that part selected at time it is defective also let X denote the number of parts inspected until a defective part is found and let p denote the probability that a randomly selected part is defective if parts are independent of each other what is P(X=i) ? What distribution describe the random variable X?

A bag manufacturer invested in a new production machine to improve its manufacturing productivity. 60% of all bags are produced by the new machine and the remaining bags by the old machine. The defect rates of the bags obtained from quality tests yields the following results Number of products tested New machine: 150 Old machine: 200 Number of defects: New machine: 30 Old machine: 60 If a quality control staff of the manufacturer selects a bag at random, what is...
