Answer 1

the answer square root of 2! just did the test and got it right :)

Explanation:

Answer 2

`√(2)` or 1.414

Explanation:

1) Find the mean. 1+2+3+4+5 = 15. 15/5= 3

2) For each data point, find the square of its distance to the mean. (4, 1, 0, 1, 4)

3) Sum the values from Step 2. 10

4) Divide by the number of data points. 10/5= 2

5) Take the square root.
