Two students want to estimate the proportion of defective pens in a large box.
Alice checks a sample of \(n = 20\) pens.
Bob checks a sample of \(n = 500\) pens.
Which estimate is likely to be more reliable?
Alice's, because smaller samples have less room for error.
Bob's, because larger samples generally provide a more precise estimation.
They are both equally reliable because they come from the same box.
