To find the absolute error and relative error, we'll follow these steps:

1. Absolute Error:

The absolute error is the difference between the measured value and the true value.

$\text{Absolute Error} = |\text{Measured Value} - \text{True Value}|$

In this case:

• True height = 61.0 inches
• Measured height = 61.4 inches

$\text{Absolute Error} = |61.4 - 61.0| = 0.4 \text{ inches}$

2. Relative Error:

The relative error is the absolute error divided by the true value, often expressed as a percentage.

$\text{Relative Error} = \frac{\text{Absolute Error}}{\text{True Value}} \times 100$

Substituting the known values:

$\text{Relative Error} = \frac{0.4}{61.0} \times 100 \approx 0.6557\%$

Final Answers:

• Absolute Error: 0.4 inches
• Relative Error: approximately 0.656%
