Question

the numbers of regular season wins for 10 football teams in a given sea 2, 0, 15, 5, 12, 8, 12, 0, 3, 7. the range is 13. (simplify your answer.) the population mean is 8.2. (simplify your answer. round to the nearest tenth as needed.) the population variance is 15.4. (simplify your answer. round to the nearest tenth as needed.) the population standard deviation is . (simplify your answer. round to the nearest tenth as needed.)

Explanation:

Step1: Recall standard - deviation formula

The formula for population standard deviation $\sigma=\sqrt{\text{Population Variance}}$.

Step2: Substitute the given variance

We are given that the population variance is $15.4$. So, $\sigma = \sqrt{15.4}$.

Step3: Calculate the value

$\sigma\approx3.9$ (rounded to the nearest tenth).

Answer:

$3.9$
