Question

What will be the mean of first 5 positive odd integers?
1. 2
2. 4
3. 3
4. 5

Answer 1

Correct Answer - Option 4 : 5

Given:

First 5 odd integers = 1, 3, 5, 7 and 9

Formula used:

Mean = Sum of observations/Number of observations

Calculation:

Sum of observations (1 + 3 + 5 + 7 + 9) = 25

Number of observations = 5

Mean = 25/5 = 5

∴ The mean of first five odd integers is 5
