<PRE><B>Question 446124</B>
The 5 participants in a 200-meter dash had the following finishing times (in seconds): 29, 25,25,31,25 
Assuming that these times constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places.
-------------------------------------
Find the mean of the data: 
mean = 27
Find the distance of each data element from the mean.
Square those number and add the squares.
Divide that sum by (# of data values -1) = 4
The standard deviation is the square root of the last number you got.
------------------
std = 2.8284..
