A set of data is found to have a μ\displaystyle \mu = 6 and a σ\displaystyle \sigma = 4.

What is σ2\displaystyle \sigma^{{2}}  for this data set?

 

Suppose each data value was divided by 5.

What is μ\displaystyle \mu  of the resulting data set?

 

What is σ\displaystyle \sigma  of the resulting data set?

 

What is σ2\displaystyle \sigma^{{2}}  of the resulting data set?
