A researcher wishes to determine the correlation between the level of rainfall (in inches) in the north Georgia area and the level of e. coli contamination levels (in parts per million) measured in the Flint River. She chose to use the rainfall measurements as the explanatory variable when she created a scatterplot. Will switching the explanatory and response variables change the calculated value of her correlation r? Question 25 options: Yes, swapping the explanatory and response variables will change the correlation coefficient r. No, swapping the explanatory and response variables will not change the correlation coefficient r. Impossible to determine
