Answer 2

Answer:

The Standard deviation is $1.414$

Step-by-step explanation:

To find the standard deviation of a set of numbers, first find the mean (average) of the set of numbers:

$\frac{94+94+92+94+96}{5} \\=\frac{470}{5} \\=94$

Second, for each number in the set, subtract the mean and square the result:

$(94-94)^{2}+(94-94)^{2}+(92-94)^{2}+(94-94)^{2}+(96-94)^{2}\\ (0)^{2}+(0)^{2}+(-2)^{2}+(0)^{2}+(2)^{2}\\0+0+4+0+4=8$

Then add all of the squares together and find the mean (average) of the squares, like this:  

$\frac{8}{5}$

Finally, take the square root of the second mean:

$\sqrt{2} =1.414$
