You may need to use the appropriate appendix table or technology to answer this question A binomial probability distribution has p 0 20 and n 100 a What are the mean and standard deviation mean standard deviation b Is this situation one in which binomial probabilities can be approximated by the normal probability distribution Explain Yes because np 5 and n 1 p 5 Yes because n 30 No because np 25 and n 1 p 5 Yes because np 5 and n 1 p 5 No because np 5 and n 1 p 5 c What is the probability of exactly 25 successes Use the normal approximation of the binomial distribution to answer this question Round your answer to four decimal places d What is the probability of 18 to 22 successes Use the normal approximation of the binomial distribution to answer this question Round your answer to four decimal places e What is the probability of 12 or fewer successes Use the normal approximation of the binomial distribution to answer this question Round your answer to four decimal place
