6. ### How do you solve?

Well, the standard deviation is : the formula is σ for standard deviation: σ = √(var_xi) where : var_xi = mean_of_(xi)^2 - [ mean_of_xi ]^2 mean_of_xi = average of the x_i mean_of_(xi)^2 = average of the x_i^2 so, easy to compute var_xi = mean_of_(xi)^2 - [ mean_of_xi ]^2 refer to my previous answer : the rest is...
