Two boxes labeled A and B are full of numbered tickets. We know that Box A has an average of 80 and an SD of 20. We also know that Box B has an average of 50 and an SD of 10. We will draw at random with replacement 100 times from Box A. Independently, we will draw at random with replacement 100 times from Box B.
From Box A: the sum of the 100 draws expected value equals SE equals the average of the 100 draws expected value equals SE equals
From Box B: the sum of the 100 draws expected value equals SE equals the average of the 100 draws expected value equals SE equals .
The difference between the sums of the draws: expected value equals SE equals (decimal form, three places) .
The difference between the averages of the draws: expected value equals SE equals (decimal form, three places).
