Hi please see my output:

Code:

           |       0.0        0.1 |       0.1

         3 |       241         63 |       304
           |       0.6        2.9 |       3.5

     Total |       806        162 |       968
           |       1.3        6.6 |       7.9

          Pearson chi2(2) =   7.8928   Pr = 0.019
I can see the p value is 0.02 however I am interested specifically to know whether there is a significant difference between groups in row 3 only. Can this be tested and produce a p value?
