You have a set of calipers that can measure thickness of a few inches with an uncertainity of ±0.005 inches. you measure the thickness of a deck of 52 cards and get 0.590 inch. a) if you now calculate the thickness of 1 card, what is my answer (including uncertainty)
b) you can improve this result by measuring several decks together. if you want to know the thickness of 1 card with an uncertainty of only 0.2 in., how many decks do you need to measure together?
