Use this data set for the following question {10,20,30,40,50}. Feel free to use Stata for this problem. If you call this data set x, the Stata command generate xnew=5*x would generate a new variable which is 5 times each element of the original data set. You can read this data set into Stata using the command a) Find the standard deviation and mean. b) Add 5 to each value, and then find the standard deviation and mean. c) Subtract 5 from each value and find the standard deviation and mean. d) Multiply each value by 5 and find the standard deviation and mean. e) Divide each value by 5 and find the standard deviation and mean. f) Generalize the results of parts b through e.
