You claim that the probability that your factory produces 15 or more de- fective widgets per day is less than or equal to 0.5. Is this claim justified? Explain your answer mathematically. (b) You have have determined that the number of defective widgets produced per day by your factory is approximately a normal distribution with mean 10 and variance 5. You claim that the probability that your factory produces 15 or more defective wid- gets per day is less than or equal to 0.02. Is this claim justified? Explain your answer mathematically.
