A farmer uses artificial insemination to impregnate his cows. This method has an 80% success rate. • Suppose 100 cows are selected at random to be inseminated. Find the mean and standard deviation of this binomial distribution. • Suppose 100 cows are selected at random to be inseminated. Use the normal approximation to the binomial distribution to find the probability that 75 or more cows become pregnant.
