Show answer & explanation
Correct answer: C
CONCEPT
The arithmetic mean of n observations equals their sum divided by n.
Equivalently, a proposed mean is consistent only when the mean multiplied by n reproduces the observations' total.
APPLICATION
Read the six Train values: 18,800, 16,600, 19,400, 18,500, 15,900, and 16,400.
Add them: 18,800 + 16,600 + 19,400 + 18,500 + 15,900 + 16,400 = 105,600.
There are 6 cities, so the mean is 105,600 ÷ 6 = 17,600.
CROSS-CHECK
Multiply the obtained mean by 6: 17,600 × 6 = 105,600, exactly the Train-column total.
Therefore, the average number of tourists travelling by Train is 17,600.
