It is reported that 50% of all computer chips produced are defective. Inspection insures that only 5% of the chips legally marketed are defective. Unfortunately. some chips are stolen before inspection. If 1% of all chips on the market are stolen, find the probability that a given chip is stolen given that it is defective. I understand the problem, but am confused how P(D|S) is .5. Why would it not be P(D) = .5 when 50% of computer chips produced...

To avoid creeps from taking covert photos, iPhones bought in Japan (and seemingly also South Korea) cannot be muted when using the camera. The mandatory shutter sound was installed to reduce voyeuristic “up-skirt” photography - especially in crowded places like rush-hour trains. The chips responsible for the camera’s sound are produced at two manufacturing plants; one in Korea, and the other in Japan. The Korean factory makes 40% of the chips, while the Japanese plant produces the remaining 60%. Quality...

A charity is holding a raffle at a fund raising event. The raffle entails all 50 attendees randomly selecting a plastic chip from a drum. The chip is a winner if it has "winner" 2. stamped on one side. In the drum are placed 100 chips with 10 being winners a. If people stand in a line, pull a chip and walk away with their chip, what is the probability of all 10 winning chips being selected? b. If the...

Question 4 (1 point) A company manufacturing computer chips finds that 8% of all chips manufactured are defective. In an effort to decrease the percentage of defective chips, management decides to provide additional training to employees. After training was implemented, a sample of 450 chips revealed only 27 defects. Using hypothesis testing we want to investigate if the additional training was effective in lowering the defect rate. Which of the following statements is true about this hypothesis test? It is...
