Answer:
8.429
Explanation:
A = {3, 5, 7, 9, 11, 12, 12}
The standard deviation is: 3.289
First find the sum, which is: 59
Then find the mean, which is: 59 divided by the amount of numbers given which is 7.
So: 59/7 = 8.429
Then you have to find the variance by using the equation:
variance^2 = [(number1 - mean)^2 + ... + ] / the count
V^2 = [(3 - 8.429)^2 + (5 - 8.429)^2 + ( 7 - 8.429)^2 + (9 - 8.429)^2 + (11 - 8.429)^2 + (12 - 8.429)^2 + (12 - 8.429)^2] all divided by 7
which equals: 10.816
the variance is the square root of 10.816 which equals 8.429
