Squared deviation

Given the data from the problem (sample data: 23, 27, 35, 44), find the sum of the squared deviations (the numerator of the fraction under the square root in the formula). In finding the number, round all calculations to 2 decimals (if you carry more or fewer, your answer may need to be corrected on this system).

Correct answer:

e =  258.75

Step-by-step explanation:

$$\begin{gathered} s=23+27+35+44=129 \\ n=4 \\ \mu =s/n=129/4=\frac{129}{4}=32\frac{1}{4}=32.25 \\ e=(23-\mu {)}^2+(27-\mu {)}^2+(35-\mu {)}^2+(44-\mu {)}^2=(23-32.25{)}^2+(27-32.25{)}^2+(35-32.25{)}^2+(44-32.25{)}^2=258.75 \end{gathered}$$
