Correct answer: A
Concept
The arithmetic mean of a set of numbers is the total of all observations divided by the number of observations.
Thus, average = total sum ÷ number of observations.
Application
Here, the total sum is 696 and the number of observations is 10.
Substitute these values: average = 696 ÷ 10.
Dividing by 10 shifts the decimal point one place to the left, so 696 ÷ 10 = 69.6.
Cross-check
Multiply the result by the number of observations: 69.6 × 10 = 696, which reproduces the given total.
Therefore, the average is 69.6.
