Question

where x represents the values, add the values. is the number of values, and Σ is the sumination symbol. which indicates that you should Do not round your answers. Step 1. Calculate the square of each data valuc. Step 2. Determine n times the sum of squares of the three values. Step 3. Calculate the sum of the three values Step 4. Calculate the square of the sum of the three values. (2x) n(n 1) Step 6. Calculate the standard deviation.

Answer 1

Solution: Given That

  

Step1:

$wH9R+hWlCDovsAAAAASUVORK5CYII=$

Step 2:

$MUIQ+benGAAAAAASUVORK5CYII=$

Step 3:

Step 4:

$inz7+G8AAAAASUVORK5CYII=$

Step 5:

= 25

Sample Variance     = 25

Step:6

Sample standard deviation = .

Therefore sample standard deviation for the given data is 5.
