The assembly line that produces an electronic component of a missile system has historically resulted in a 2% defective rate. A random sample of 800 components is drawn. What is the probability that the defective rate is greater than 4%? Suppose that in the actual random sample drawn the defective rate is 4%. What does that suggest about the defective rate on the assembly line?
