9.) Data set "A" has five elements: A = {82, 87, 92, 94,80). Create a data set “B” such that each element of set B is 1 less than those in set A. Now, create a data set “C” such that each element of set C is 2 more than set A.

What is the mean, median, range, variance, and standard deviation of sets A, B, and C?
Explain your observations about these values.
