A

Step-by-step explanation:

 is the standard deviation of x.

The standard deviation is gotten by:

1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)

2. subtract the average, x bar, from each of the values, square it,  and add up the difference

3. Divide that final answer by n, which is 5

4. Take the square root of the answer

Now, let's find the average (x bar):

x bar =

Doing steps 2 & 3 together:

Doing step 4:
