 Question 334154: The ages (in years) of the employees at a particular computer store are 36,40,24,24,31 Assuming that these ages constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places. Answer by jrfrunner(365)   (Show Source): You can put this solution on YOUR website!1. compute the average: add the values and divide by 5 Average =(36+ 40+24+24+31)/5=31.0 -- 2. Compute the deviations from the average dev: (36-31)=5, (40-31)=9,etc -- 3. Square the deviations and add sum (dev^2): 5^2+9^+...+0^2=204 -- 4. Divide step #3 by the sample size=5 (typically you divide by sample size-1 to get the sample standard deviation, but you are assuming the 5 values are the population, so no need to subtract 1, from the sample size. This result is the variance Variance =204/5=40.8 -- 5. Standard deviation = sqrt(variance) standard deviation= sqrt(40.8)
