Hover to see experimental set-up.

You are offered a choice between two boxes, A and B. Each of these boxes are randomly picked from the 200 boxes. You will be paid $10 if you pick a golden box if this choice is selected for payment. Box A and B are randomly picked the following way:

  1. Box A was picked as follows:
    1. We drew 4 balls from each of the 200 boxes. They were drawn one at a time, replacing each ball to the box after it was drawn.
    2. {% if player.treatment == 'sym' %}
    3. 25 out 200 boxes had 4 out 4 red balls drawn from them (no blue balls were drawn).
    4. Box A was randomly selected from these 25 boxes.
    5. {% elif player.treatment == 'asy' %}
    6. 52 out 200 boxes had 4 out 4 red balls drawn from them (no blue balls were drawn).
    7. Box A was randomly selected from these 52 boxes.
    8. {% elif player.treatment == 'amb' %}
    9. 29 out 200 boxes had 4 out 4 red balls drawn from them (no blue balls were drawn).
    10. Box A was randomly selected from these 29 boxes.
    11. {% endif %}

  2. Box B was picked as follows:
    1. We randomly picked Box B from the 200 boxes.
    2. We will draw 25 balls, one at at time with replacement, from Box B.
    3. You can make your choice based on the number of red balls that we draw from B.

{{ formfield_errors "p25comp4" }} {% for item in right_side_amounts_percentages %} {% endfor %}
Choose Box A Choose Box B
Box A - 4 out of 4 (100%) balls drawn were red.    Box B - if {{ item.amount }} out of 25 ({{ item.percentage }}%) balls drawn are red.

You may wonder if there is a "correct" choice to the above. Indeed, it is possible, using statistical theory, to calculate the choice for each row that would give you the highest probability of winning $10. You may not know what the correct choice is, therefore, we offer you after each decision a chance to learn the correct choice and change your choices. In particular, we offer you three options:
