Answer 2

Answer:

6 10 12 14 80

80 is the outlier away from the data set trend

The mean and Sd Wii be affected

Mean = (6+10+12+14+80)/5 =24.5(assuming 24)

D^2= 18^2 +14^2 +12^2 +10^2 +56^2

=324 +196+144+100+3136 =3900

Sd= (3900/4)^1/2 =(975)^1/2 =31.2

Variance =(31.2)^2=973.4

If remove outlier

Then the mean is =42/4=10.5(11)

D^2=25+1+1+9=36

Variance =36/3=12
