The table shows the height of some students in a school. Calculate correct to one decimal place, the Mean, Standard deviation, and Mean deviation of the distribution.

We are given that $PQ \parallel RS$.
We have $\angle TPQ = 32^\circ$ and $\angle TRS = 38^\circ$.
We need to find the value of angle $g$, which is $\angle PTR$.

Let's draw a line $XY$ passing through $T$ such that $XY \parallel PQ \parallel RS$.

Since $PQ \parallel XY$, the alternate interior angles are equal.
Therefore, $\angle PTX = \angle TPQ = 32^\circ$.

Since $RS \parallel XY$, the alternate interior angles are equal.
Therefore, $\angle RTX = \angle TRS = 38^\circ$.

From the diagram, angle $g$ is the sum of $\angle PTX$ and $\angle RTX$.

The value of the angle marked $g$ is $\boxed{\text{70}^\circ}$.
