A manufacturing machine has a 65% defect rate. If 125 items are chosen at random, answer the following.
a) Which is the correct wording for the random variable?
rv X = a randomly selected item that is defective
Select an answer
rv X = all items that are defective
b)
rv X = is defective
rv X = a randomly selected item
c) rv X= the number of randomly selected items that are defective
rv X = the number of 125 randomly selected items that are defective
rv X = a randomly selected item that is defective
d) rv X = the probability that a randomly selected item is defective
