1. Consider an assembly line where 2% of the units produced are defective. 2% 98% XX You will take a random sample of 100 units from this assembly line. a. What is the average number of defective units per sample (the expected value)? What is the standard deviation? b. What is the probability that the number of defective units in the sample will exceed the expected number by at least 1 standard deviation*? At least 2 standard deviations? At least 3 standard deviations? *By this I mean "What is P(X + o)?" 1.
