For the data values 69, 54, 27, 43, 69, 56, the mean is 53.The sample standard deviation of these numbers is calculated below. Fill in the blanks for the missing parts of this calculation.

Answer 1

Answer:

3 and 9

Explanation:

The mean of the data values = 53

When x=56

$x-\operatorname{mean}=56-53=3$

Therefore, fill the blank in the first column with 3.

Next, take the square:

$(x-\operatorname{mean})^2=3^2=9$

Therefore, fill the blank in the second column with 9.

The filled table is attached below:
