Question

The variance of the sample data is?

Answer 1

12.4523 kg

Explanation:

The variance is found by averaging the square of the deviance (how far a number is from the mean) of each number.

Since we found the average of the deviance, all we have to do now is square that, and divide by the number of subjects.

11.1590² = 124.5232 --> 124.5232/10 = 12.4523 kg
