Assume a binomial probability distribution has p = .60 and n = 200.

1. What are the mean and standard deviation (to 2 decimals)?
2. Why can the normal probability distribution be used to approximate this binomial distribution?

What is the probability of 100 to 110 successes (to 4 decimals)? What is the probability of 130 or more successes (to 4 decimals)? What is the advantage of using the normal probability distribution to approximate the binomial probabilities
