Question 1: Suppose that of 6,000 electrical fuses, 5% are defective. Also, suppose that a random sample of 10 fuses is selected and consider the random variable X representing the number of defective fuses in the sample. (a) Explain why a binomial distribution is appropriate. (b) What is the probability that at least one of the fuses is defective? (c) What is the probability that fewer than 3 fuses are defective?

Question 2: Refer to the setup in Question 1. Suppose that a random sample of size n = 200 is instead drawn and again let X be the random variable representing the number of defective fuses in the sample. (a) Find the mean and standard deviation of X. (b) Estimate the probability that no more than 15 fuses are defective

an electronics company finishes a production run of 5000 tablet computers, which includes 900 defective units. To test this batch for defects, a random sample of 100 tablets is drawn (without replacement) and tested. Let X be the random variable that counts the number of defective units among the sample. a. find the expected (mean) value, variance, and standard deviation of X b. the probability distribution of X can be approximated with a binomial distribution. Why?   c. Use the binomial...

suppose 2% of items produced from as assembly line are defective if we sample 10 items what is the probability that 2 or more are defective ?here count follows the binomial distribution. suppose now that we sample 10 items from a small collection like 20 items and count the number of defectives. resulting random variable is not binomial .why not?
