Jonathan and Tim want to predict how many quarters are in a large jar containing 120 coins. Jonathan randomly selects a sample of 10 coins from the jar, while Tim randomly selects a sample of 30 coins. Then they count the number of quarters in each sample. Whose sample should more accurately predict the number of quarters in the jar?

Jonathan’s Tim’s sample should give a more accurate prediction of the number of quarters in the jar. @brooke..help00 @michaelbp

Tim would have a more accurate prediction because say there were 15 quarters in his hand of thirty coins, that would be 15 quarters for every 0 in the jar. (Please medal)
