(c) Compute the sample correlation coefficient r for each of the following data sets and show that r is the same for both. (Use 3 decimal places.) (a) Look at the data below regarding the variables x = age of a Shetland pony and y = weight of that pony. Is the value of Ir large enough to conclud that weight and age of Shetland ponies are correlated? Use a = 0.05. (Use 3 decimal places.) x y 3 60...
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....
