Question: Suppose x is a binomial random variable with p = 0.4 and n = 25. a. Would it be appropriate to approximate the probability distribution


Suppose x is a binomial random variable with p = 0.4 and n = 25. a. Would it be appropriate to approximate the probability distribution of x with a normal distribution? O A. No, because pit 30 lies within the boundaries of 0 and 25. O B. No, because u + 30 lies outside the boundaries of 0 and 25. C. Yes, because u + 30 lies within the boundaries of 0 and 25. O D. Yes, because p 1 30 lies outside the boundaries of 0 and 25. b. Assuming that a normal distribution provides an adequate approximation to the distribution of x, what are the mean and variance of the approximationg normal distribution? Or The mean is or The variance is
