Best ResponseYou've already chosen the best response.0You given 6 x_i values. The equation only wants you to consider x_i for (i=1 until i=3), that would be x1, x2, x3. The sigma is the symbol for sum. So the problem is to find the sum for the following events: plugging in each x_i subtracting 1 then squaring that. Hence you'll have 3 values that you then add to together to get the final value. \[ i=1, x_1 = 2, (21)^2 = 1\] \[i=2, x_2 = 1, ((1) 1)^2 = ... \] ... and so on
