What is the average of the cube root of the first 5 positive numbers having a perfect cube root? Correct Answer 3

Formula used:

Average = Sum of all observation/Total number of observations

Calculation:

According to the question

First five positive number having perfect cube root are = 1, 8, 27, 64, and 125

Their respective cube roots = 1, 2, 3, 4, and 5

Average = (1 + 2 + 3 + 4 + 5)/5

⇒ 15/5

⇒ 3

∴ The average is 3.
