This is the concept of probability and statistics, to get the summation of (x-μ) where μ is the mean will be given by:
(3.7-11)+(8.2-11)+(9.9-11)+(9.9-11.3)+(15.6-11)+(17.3-11)
=-7.3+-2.8+-1.1+0.3+4.6+6.3
=0

Answer: 0

Step-by-step explanation:

Let x_i be the data values.

Then the mean of data is represented by \bar{x}.

Now, Consider\sum_{i=1}^{6}(x_1-\bar{x})=(x_1-\bar{x})+(x_2-\bar{x})+(x_3-\bar{x})+(x_4-\bar{x})+(x_5-\bar{x})+(x_6-\bar{x})

=(3.7-11)+(8.2-11)+(9.9-11)+(11.3-11)+(15.6-11)+(17.3-11)\\\\=-7.3-2.8-1.1+0.3+4.6+6.3=0

Hence, the value of \sum_{i=1}^{6}(x_1-\bar{x})=0
