Give table of values

Here is the table of values. You will need to fill in the experimental times ($t_1$, $t_2$) and then calculate the corresponding periods ($T_1$, $T_2$) and their squares ($T_1^2$, $T_2^2$).

$$\begin{array}{|c|c|c|c|c|c|c|c|} \hline \text{Mass } m \text{ (g)} & \text{Mass } m \text{ (kg)} & t_1 \text{ (s)} & T_1 = \frac{t_1}{10} \text{ (s)} & T_1^2 \text{ (s}^2\text{)} & t_2 \text{ (s)} & T_2 = \frac{t_2}{10} \text{ (s)} & T_2^2 \text{ (s}^2\text{)} \\ \hline 150 & 0.150 & & & & & & \\ 200 & 0.200 & & & & & & \\ 250 & 0.250 & & & & & & \\ 300 & 0.300 & & & & & & \\ 350 & 0.350 & & & & & & \\ \hline \end{array}$$
