From the table given,

To find the x - mean,

By the summation of all the x - mean

The value of x - mean is

[tex]x-\operatorname{mean}=16+1-26-10+16=-3[/tex]

Hence, the value of x - mean is -3

To find the (x - mean)²

By the summation of all the values of (x - mean)²

The value of (x - mean)² is

[tex](x-\operatorname{mean})^2=256+1+676+100+256=1289[/tex]

Hence, the value of (x - mean)² is 1289
