The bars in the graph represent total orders prepared, and the lines represent late orders.
Select from each drop-down menu the option that completes the statement most accurately based on the information provided.
For Center A, the probability that an order selected at random was delivered late was greatest in .
Among the months in which Center B prepared more orders than Center A, the difference between the numbers of late orders at the two centers was greatest in .
Official Solution:
Drop-down 1:
Here we need the proportion of Center A’s orders that were late, not simply the number of late orders.
For each month, compare the height of Center A’s late-orders point with the height of its total-orders bar. Among the answer choices, April has the largest ratio:
8/45 ≈ 18%
This is greater than the corresponding proportion in the other listed months.
Therefore, the probability was greatest in April.
Drop-down 2:
First, compare the total-orders bars and consider only the months in which Center B’s bar is higher than Center A’s. These are January, March, April, June, and August.
Now compare the two late-orders points only for those months. The largest vertical separation occurs in August:
Center A: about 4 hundred late orders
Center B: about 9 hundred late orders
The difference is about 5 hundred orders, larger than in any of the other qualifying months.
Therefore, the correct selection is August.
Correct answer:
Drop-down 1: "April"
Drop-down 2: "August"
