I think the answer would be 8+9
<span>100000 + 2000 + 500 + 150 + 17 +0.08
= 102000 + 500 + 150 + 17 + 0.08
= 102500 + 150 + 17 + 0.08
= 102650 + 17 + 0.08
= 102667 + 0.08
= 102667.08 <--</span>
Mean = (14 + 16 + 7 + 9 + 11 + 13 + 8 + 10) ÷ 8 = 11
Variance =
[ (14-11)²+(16-11)²+(7-11)²+(9-11)²+(11-11)²+(13-11)²+(8-11)²+(10-11)² ]/7 = 9.71
Answer: 9.71
