Is the relationship between x and y approximatelylinear, or is it nonlinear?b. Compute the natural logarithm of each y value. This is known as making a logtransformation of y. Make a scatterplot of In y versus x. Is the relationship between xand In y approximately linear, or is it nonlinear?In general, it is easier to work with quantities that have an approximate linearrelationship than with quantities that have a nonlinear relationship. For these data, doyou think it would be easier to work with x and y or with x and In y? Explain.a.C.
