A quаlity cоntrоl mаnаger at a manufacturing plant is analyzing the defect rate оf a component. They know that historically, 5% of all components produced are defective. Scenario 1: The manager wants to estimate the probability that in a random sample of 100 components, exactly 7 are defective. Scenario 2: The manager wants to estimate the probability that the average weight of a random sample of 1000 components falls within a specific range, given that the component weights are approximately normally distributed. Which of the following statements is MOST accurate regarding the appropriate probability distribution to use in each scenario?
