Correct Answer - Option 1 : 8
Given
Numbers are 5, 8, 0, 12 and 15
Formula used
Average = total sum of all observations/total number of observations
Calculation
The sum of all observations = 5 + 8 + 0 + 12 + 15
⇒ 40
Number of observations = 5
Average = total sum of all observations / total number of observations
⇒ 40/5
⇒ 8
∴ The average is 8.
