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:

s=23+27+35+44=129 n=4 μ=s/n=129/4=4129=3241=32.25  e=(23μ)2+(27μ)2+(35μ)2+(44μ)2=(2332.25)2+(2732.25)2+(3532.25)2+(4432.25)2=258.75
