15. In approximating the Binomial with the Normal distribution, it is necessary to have a mean and standard deviation. If the Binomial has n = 200 and the probability of a success p = 0.1, what mean and standard deviation should be used for the Normal approximation? A. Mean 180, standard deviation = 4.24 = B. Mean = 20, standard deviation = 11.31 C. Mean = 20, standard deviation = 4.24 D. Can't tell 16. The wingspan of the Monarch butterfly is normally distributed with a mean area of 44 mm² and a standard deviation of 8.7 mm².
