#### Answer

mean = 100 standard deviation = 7.23

#### Work Step by Step

$102, 98, 103, 86, 101, 110$ $102+98+103+86+101+110$ $200+189+211$ $600$ $600/6 = 100$ $(102-100)^2+(98-100)^2+(103-100)^2+(86-100)^2+(101-100)^2+(110-100)^2$ $2^2+(-2)^2+3^2+(-14)^2+1^2+10^2$ $4+4+9+196+1+100$ $13+200+101$ $314$ $314/6 = 52.33$ $\sqrt {52.33} = 7.23$
