Can a normal distribution always be used to approximate a binomial distribution? Explain your answer. O No. For the approximation to be accurate, np > 5 and ng < 5. No. For the approximation to be accurate, np > 10 and ng > 10. O No. For the approximation to be accurate, np > 5 and ng > 5. Yes. We can always use the normal distribution to approximate the binomial distribution.
