The 6 participants in a 200 -meter dash had the following finishing times (in seconds). \[ 25,26,28,27,27,29 \] Send data to calculator Assuming that these times constitute an entire population, find the standard deviation of the population. Round your answer to two decimal places.

Step 1 ：The 6 participants in a 200-meter dash had the following finishing times (in seconds): \(25, 26, 28, 27, 27, 29\).

Step 2 ：We first need to find the mean (average) of the data. The mean is \(27.0\).

Step 3 ：Next, for each number in the data, we subtract the mean and square the result. The squared differences are \(4.0, 1.0, 1.0, 0.0, 0.0, 4.0\).

Step 4 ：We then find the mean of these squared differences. This is called the variance. The variance is \(1.6666666666666667\).

Step 5 ：Finally, we take the square root of the variance to get the standard deviation. The standard deviation is \(1.29\).

Step 6 ：Final Answer: The standard deviation of the population is \(\boxed{1.29}\).
