"For Chapter 12 Data Set 2, compute the t value manually and write a conclusion as to whether there was a change in tons of paper used as a function of the recycling program in 25 different districts. (Hint: Before and after become the two levels of treatment.) Test the hypothesis at the .01 level."

The table presents two sets of data labeled as "Before" and "After," each with two columns. The values in the table are as follows:
