Solution

Solution Steps

Step 1: Identify the second class

The second class in the GFDT is $170-179$.

Step 2: Calculate the class midpoint

The class midpoint is calculated using the formula: \[ \text{Midpoint} = \frac{\text{Lower Bound} + \text{Upper Bound}}{2} \] For the second class $170-179$: \[ \text{Midpoint} = \frac{170 + 179}{2} = \frac{349}{2} = 174.5 \]

Step 3: Present the result

The class midpoint for the second class is $174.5$.
