Five hundred draws are made at random with replacement from a box with 10,000 tickets. The average of the box is unknown. However, the average of the draws was 71.3, and their SD was about 2.3. Which one is true? (a) A 68% - confidence interval for the average of the box is 71.3 +- 0.1 (b) About 68% of the tickets in the box are in the range of 71.3 +- 0.1 (c) The 71.3 estimates the average of the box, but is likely to be off by 2.3 or so
