A manufacturing machine has a 40% defect rate. If 131 items are chosen at random, then:
The random variable, X=Number of 131 randomly selected items that are defective.Number of Items, n=131The point estimate of defective items, p=40%=0.4Ответ:
304
Step-by-step explanation: x/760 40/100=
760x40=30,400
30,400 divided by 100=304
