Q. Sandeep tossed a fistful of silver coins into the air, then picked up the 77 coins that landed heads up.\newlineIs this sample of the coins likely to be representative?\newlineChoices:\newline(A)yes\newline(B)no
  1. Understand the problem: Step 11: Understand the problem.\newlineSandeep tossed a bunch of silver coins and picked up 77 that landed heads up. We need to decide if these 77 coins are a good sample of all the coins tossed.
  2. Analyze sample representativeness: Step 22: Analyze the likelihood of the sample being representative.\newlineSince the coins are randomly tossed and only the ones showing heads are picked, the sample might not represent the total number of coins tossed, especially if the total number was much larger than 77.
  3. Consider randomness and bias: Step 33: Consider the randomness and bias.\newlineThe sample is biased because it only includes coins that landed heads up. This doesn't consider coins that landed tails up, which could be about half of the total coins tossed.
  4. Make conclusion: Step 44: Make a conclusion based on the analysis.\newlineThe sample of 77 coins is not likely to be representative of the total number of coins tossed, as it only includes heads and ignores any tails.
