Guesstimation: Part II
I recently invited readers to try to guess the total value of the coins in this piggy bank. I’ll share that data shortly, but I wondered how accurately someone could estimate the total value of the piggy bank if they knew the weight?
The full piggy bank weighed out to around 2996 grams. I took some other weighings to find that a penny weighs approximately 2.7 g; a nickel is approximately 4.9 g; a dime is approximately 2.3 g; and a quarter is approximately 5.6 g.
Armed with this information, how much more accurate might the estimates be?
