Correct Answer - Option 2 : 49
Given:
Data: 54, 81, 28, 84, 32, 21, 43
Concept:
The mean is the average of the numbers.
It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.
Calculation:
Mean = (54 + 81 + 28 + 84 + 32 + 21 + 43)/7
⇒ 343/7 = 49
∴ The mean of given data is 49
