On average, how many transistors would you expect to be produced until the first with a defect? What is the standard deviation? Mean = 1/p Standard deviation = sqrt(q/p^2) p is the probability of a success on any given trial q is the probability of failure on any given trial By substituting the given values into the formula, we calculate: Mean = 1/0.02 = 50 Standard deviation = sqrt(0.98/0.02^2) = 49.50 On average, we would expect to produce 50 transistors before the first unit produced with defect. The number of transistors being produced before the first unit being defective can vary by about 49.50 transistors around the mean of 50. is this correct
