1. A process for producing a particular kind of computer chip yields 60% good chips.

(a) What is the probability that a random sample of 5 of these chips has 4 or more good chips?

Let X be the number of good chips in a random sample of size 100.

(b) Give the numerical value of the mean of the random variable X, μX.

(d) Use the normal approximation to the binomial distribution to evaluate P(X < 50)

Hint

StatisticsBinomial distribution is a probability distribution which summarizes the likelihood that a value would take one of the two independent values under the given set of parameters or even assumptions. This distribution is a very common discrete distribution which is used in the statistics....
