Compute by hand the t(rel) statistic: (Do not run through the 7 steps of a significance test)

t-test data: Use the data below to determine t-obtained value. I do not need to see your work, but you need to identify the 4 values you used to complete the calculations. (Full answer contains 5 separate values)

                      pre-Tx:         post-Tx:

                             7                   8                                                                                     

                             2                   9
