Suppose you take a random sample of 25 from a lot of 1,000 items but later realize that you should have selected a sample of 40 items instead. How do you correct this error? Should you put the 25 items back and draw the required random sample of 40 from the original lot, or should you simply draw an additional random sample of 15 from the 975 remaining items?
