Answer 1

Answer:

The values of x are: 9.8,5.4,3.7,1.7,1.8,2.6,2.8,8.6,10.5,11.1

Mean =

Total Numbers

Sum

Mean =

10

9.8+5.4+3.7+1.7+1.8+2.6+2.8+8.6+10.5+11.1

Mean =

10

58

= 5.8

Now,

∑(x−

x

ˉ

) = (9.8−5.8)+(5.4−5.8)+(3.7−5.8)+(1.7−5.8)+(1.8−5.8)+(2.6−5.8)+(2.8−5.8)+(8.6−5.8)+(10.5−5.8)+(11.1−5.8)

= 4−0.4−2.1−4.1−4−3.2−3.0+2.8+4.7+5.3

= 0
