The correct Answer is:
To find the most probable median given the mode and mean of a moderately asymmetrical series, we can use the relationship between these measures of central tendency. The formula we will use is: \[ 3 \times \text{Median} = 2 \times \text{Mean} + \text{Mode} \] ### Step-by-step Solution: 1. **Identify the given values**: - Mode = 16 inches - Mean = 15.6 inches 2. **Substitute the values into the formula**: \[ 3 \times \text{Median} = 2 \times 15.6 + 16 \] 3. **Calculate \(2 \times \text{Mean}\)**: \[ 2 \times 15.6 = 31.2 \] 4. **Add the Mode to this result**: \[ 31.2 + 16 = 47.2 \] 5. **Now, divide by 3 to find the Median**: \[ \text{Median} = \frac{47.2}{3} = 15.7333 \text{ inches} \] 6. **Round to two decimal places** (if required): \[ \text{Median} \approx 15.73 \text{ inches} \] ### Final Answer: The most probable median is approximately **15.73 inches**.
