17. Assume that we apply a square root transformation to a ratio attribute r to obtain the new attribute r. As part of your analysis, you identify an interval (a, b) in which r* has a linear relationship to another attribute y. (a) What is the corresponding interval (a, b) in terms of r? (a?, b²) (b) Give an equation that relates y to r. In this interval, y = r.
