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) result? Explain your answer.
The result is different because the formula is dependent on the
symbols.The result is the same because the formula is dependent on
the symbols. The result is the same
because the formula is not dependent on the symbols.The result is...
