a company manufactures video games with a current defect rate of 0.95%. to make sure as few defective video games are delivered as possible, they are all tested before delivery. the test is 98% accurate at determining if a video game is defective. if 100,000 products are manufactured and delivered in a month, approximately how many defective products are expected to be delivered? 20 50 2,000 950
Answer
Explanation:
Step1: Calcular el número real de productos defectuosos
El porcentaje de productos defectuosos es del 0.95%. Si se fabrican 100000 productos, el número real de productos defectuosos es $100000\times0.0095 = 950$.
Step2: Calcular el número de productos defectuosos detectados
El test es 98% exacto en detectar productos defectuosos. Entonces, el número de productos defectuosos detectados es $950\times0.98=931$.
Step3: Calcular el número de productos defectuosos no detectados
El número de productos defectuosos no detectados es $950 - 931=19\approx20$.
