1. A scatterplot of the price of one pound of Nabisco Oreo cookies versus year from 1932 through 2012 shows a distinctly curved relationship. However, the appropriate transformation for an exponential relationship of price versus year produces a linear scatterplot. Below is computer output for a regression analysis of the transformed data.
