The initial visual impact of a scatter diagram depends on the scales used on the x and y axes. Consider
the following data.

Examine the computation formula for r, the sample correlation coefficient.
(a) In the formula for r, if we exchange the symbols x and y, do we get a different result or do we get
the same (equivalent)
