Estimate the standard deviation of the Japanese car population (s or ). (Report the answer with 3 decimal points. Remember to use the formula for Provide your calculation process.) Standard Deviation (s) = 3.182 Standard Deviation (s) 3.1817934 Standard Deviation (s = 3.1817934) Variance (s^2 = 10.12381 Count (n = 15) Mean (x = 32.866667) Sum of Squares (SS = 141.73333) sqrt[((x_i - )^2) / (n-1)] x_i represents each score, is the mean, and n is the number of scores. sqrt[((28-32.867)^2+(29-32.867)^2 +(29-32.867)^2+(30-32.867)^2 +(30-32.867)^2 +(32-32.867)^2+(32-32.867)^2+(33-32.867)^2+(34-32.867)^2+(34-32.867)^2+(35-32.867)^2+(36-32.867)^2+(36-32.867)^2+(37-32.867)^2+(38-32.867)^2 = 11.905
