A) Draw a scatterplot of the untransformed data and tell which kind of relationship the points seem to follow. Also name the best type of transformation needed to "straighten" the plot.

B) Now try some transformations to get the data as close to linear as possible. (Transform the data, and try scatterplots of the different transformations). Then find the regression line, r, and r².Tell which transformation worked the best and back it up by showing: A scatterplot of the transformed data with the least-squares regression equation and line, r, and r-squared and a plot of the original data with the regression equation converted to a non-linear equation.

C) Using the transformed data and the regression equation for it, draw a plot of residuals vs. x-values. Sketch the plot and interpret it.
