a. 25.000
b. 1,0204% Lo
Penjelasan dengan langkah-langkah:
x = 2.450.000
x.i = 2.850.000
Z = 16
a. ditanyakan simpangan baku (S)
Z = (x.i - x)/S
S = (xi - x)/Z
= (2.850.000-2.450.000)/16
= 400.000/16
= 25.000
b. koefisien variannya
x = rata rata
KV = S/x .100%
= 25.000/2450.000 x 100%
= 1,0204 %
langkah pengerjaan terlampir
