Answer:

1.7

Step-by-step explanation:

Verified correct in a K12 test, but I looked up how to do it... A calculator is the easiest way!!  :o

From mathisfun website:

  • Work out the Mean (the simple average of the numbers)
  • Then for each number: subtract the Mean and square the result.
  • Then work out the mean of those squared differences.
  • Take the square root of that and we are done!
