Let's say you have two variables say forearm circumference and strength and you initially use forearm circumference as the explanatory variable, x ,and strength as the response variable, y, when constructing a best fit line. Let's say you get the following equation... strength 2 b + m - (forearm circumference) That is, given a forearm circumference, one can predict the strength. Now let's say you want to switch the roles of the variables and now you want to use strength as the explanatory variable, x, and forearm circumference as the response variable, y. Discuss if you can use this same equation to predict forearm circumference from strength. That is, given a strength can you predict forearm circumference by substituting the given strength into the above equation and solving for the forearm circumference? Please make sure you comment on why you can, or can't
