1. The problem asks for the fraction of members whose heights are between 150 cm and 160 cm. 2. From the frequency polygon and table, the class interval 150 < x ≤ 160 corresponds to the midpoint 155 cm. 3. The frequency for this class is approximately 8 members. 4. To find the fraction, we need the total number of members. Sum all frequencies: $$2 + 3 + 13 + 8 + 4 = 30$$ 5. The fraction of members between 150 and 160 cm is: $$\frac{8}{30} = \frac{4}{15}$$ 6. Therefore, the fraction of members between 150 and 160 cm tall is $\frac{4}{15}$.
