A sample of 68 objects had the following results:

 x\displaystyle \overline{{x}} = 141

The median = 142

S\displaystyle {S} = 2.

Suppose 11 was added to each of the numbers in the dataset.

What is the x\displaystyle \overline{{x}} of the resulting dataset?

 

What is the median of the resulting dataset?

 

What is the S\displaystyle {S} of the resulting dataset?

 

What is the S2\displaystyle {S}^{{2}}  of the resulting dataset?
