A company manufactures eyeglasses for different retailers. In March 2010, they tested to see how many defective lenses they made, and there were 16.4% defective lenses due to scratches. Suppose the company examined twenty- five eyeglasses. State the random variable. The number of defective lenses. The number of lenses that were scratched. The type of defect. Round your answers to four decimal places, if necessary. Find the probability that None are scratched. P(x = 0) = All are scratched. P(x = 25) = At least sixteen are scratched. P(x16) = At most thirteen are scratched. P(x < 13) = At least five are scratched. P(x > 5) = Is it unusual for at least five lenses to be scratched? Yes, because the probability is less than 0.05. Yes, because the probability is at least 0.05. No, because the probability is less than 0.05. No, because the probability is at least 0.05. A company manufactures eyeglasses for different retailers.
