sigma equals square root of fraction numerator 100 squared plus 150 squared plus 200 squared plus 250 squared plus 360 squared plus 490 squared plus 500 squared plus 600 squared over denominator 8 end fraction minus 331.25 squared end root
equals square root of 139337.5 minus 109726.5625 end root
equals square root of 29610.938 end root
equals 172.078
C. V equals fraction numerator sigma over denominator x with bar on top end fraction equals fraction numerator 172.078 over denominator 331.25 end fraction equals 0.52 space o r space 52 percent sign
