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 random sample the defective rate is 4%. What does that suggest about the rate on the assembly line?
(a) Mean, m = np = 800 * 0.02 = 16, sd = sqrt [np(1 - p)] = sqrt [800 * 0.02 * 0.98] = 3.96
x = 0.04 * 800 = ...
Step-by-step solution is provided.
