Answer:

Set A has a college student population with the sum closest to 78,000.

Explanation:

-------------------------------------------------------------------------------------------------------------

First, we need to determine the sums of college student populations.

Set 1: 18,432 + 32, 761 + 27, 390 = 78, 583

Set 2: 15, 791 + 47, 318 + 27, 522 = 90, 631

Set 3: 22, 109 + 38, 569 + 32, 780 = 93, 458

Set 4: 27, 420 + 47, 338 + 22, 183 = 96, 941

-------------------------------------------------------------------------------------------------------------

Now we determine the difference in populations between the given sets and 78,000...

Step 1: 78, 583 - 78, 000 = 583

Step 2: 90, 631 - 78, 00 = 12, 631

Step 3: 93, 458 - 78, 000 = 16, 458

Step 4: 96, 941 - 78, 000 = 18, 941

-------------------------------------------------------------------------------------------------------------

Thus, the answer to your problem is, Set A.
