The mean x and standard deviation s measure center and varia

The mean x^- and standard deviation s measure center and variability but are not a complete description of a distribution. Data sets with different shapes can have the same mean and standard deviation. Find x^- and s for data set A. X^-= s= Find x^- and s for data set B. x^-= s=
