Now that the values n, = noT = nc = nsA = 10, the overall sample mean x = 61.2, and the individual sample means x = 49.8, XpT = 64.3, XC = 69.1, and XSA = 61.6 are known, the SSTR can be found. Find this value. k SSTR = >n ( x, - X)2 j = 1 = n_ ( XL - x) 2 + npT (XpT - x) 2 + nc ( xc - x) 2 + ngA ( XSA - *)2 = 10(49.8 - 61.2)2 + 10(64.3 - 61.2)2 + 10(69.1 - 61.2)2 + 10(61.6 - 61.2)2 = Submit Skip (you cannot come back)
