Discussion:
Q: Assume a binomial probability distribution has µ=0.60 and n= 200
a. What is the mean and standard deviation?
b. Is this a situation in which binomial probabilities can be approximated by the normal probability distribution? Explain
c. What is the probability of 100 to 110 successes?
d. What is the probability of 130 or more successes?
e. What is the advantage of using the normal probability distribution to approximate the binomial probabilities? Use part (d) to explain the advantage
