Essay

QuarkNet,a project funded by the National Science Foundation and the U.S.Department of Energy,poses the following problem on its website:
"Last year,deep within the Soudan mine,QuarkNet teachers began a long-term experiment to measure the amount of carbon-14 remaining in an initial 100-gram sample at 2000-year intervals.The experiment will be complete in the year 32001.Fortunately,a method for sending information backwards in time will be discovered in the year 29998,so,although the experiment is far from over,the results are in."
Here is a portion of the data:
A scatterplot of these data looks like:
Straighten the scatterplot by re-expressing these data and create an appropriate model for predicting the mass from the year.
