Based on the given information, the following two-way table is obtained.

$$\begin{array}{|c|c|}\hline & \text{Tes} & \text{No} & \text{Total} \\ \hline \text{Improved} & 34 & 12 & 46 \\ \hline \text{Condition} \\ \hline \text{Did not improve} & 10 & 29 & 39 \\ \hline \text{Total} & 44 & 41 & 85 \\ \hline \end{array}$$

The marginal frequencies are derived by summing the entries corresponding to rows and columns.
