A stationary store has decided to accept a large shipment of ball-point pens if an inspection of 15 randomly selected pens yields no more than two defective pens. (a) Find the probability that this shipment is accepted if 5% of the total shipment is defective. (Use 3 decimal places.) (b) Find the probability that this shipment is not accepted if 15% of the total shipment is defective. (Use 3 decimal places.)

A stationery store has found that 5% of ball-point pens are defective. The store will accept a large shipment if an inspection of 25 randomly selected pens contains no more than 2 defective pens. Find the probability that the shipment will be accepted. Probability = (round answer to three decimal places)

Suppose a shipment of 130 electronic components contains 3 defective components. To determine whether the shipment should be accepted, a quality-control engineer randomly selects 3 of the components and tests them. If 1 or more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?
A shipment of 30 inexpensive digital watches, including 10 that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected? The probability the shipment will be rejected is _______ . (Simplify your answer. Type an integer or decimal rounded to two decimal places as needed.)
Suppose you just received a shipment of thirteen televisions. Three of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work?
For each shipment of parts a manufacturer wants to accept only those shipments with at most 10% defective parts. A large shipment has just arrived. A quality control manager randomly selects 50 of the parts from the shipment and finds that 6 parts are defective. Is this sufficient evidence to reject the entire shipment? Use a .05 level of significance to conduct the appropriate hypothesis. [15 Marks]
suppose you just received a shipment of eight televisions. three of the televisions are defective. if two televisions are randomly selected, compute the probability that both televisions work. what is the probability at least one of the two televisions does not work? The probability that both televisions work is (Round to three decimal places as needed.) The probability that at least one of the two televisions does not work is nothing. (Round to three decimal places as needed.)
A manufacturer receives a lot of 270 parts from a vendor. The lot will be unacceptable if more than 12 of the parts are defective. The manufacturer is going to select randomly k parts from the lot for inspection and the lot will be accepted if no defective parts are found in the sample. • (a) How large does K have to be to ensure that the probability that the manufacturer accepts an unacceptable lot is less than 0.20? •...
