To calculate the absolute error from the percent error, we can use the following formula:
\[ \text{Absolute Error} = \left(\frac{\text{Percent Error}}{100}\right) \times \text{Actual Value} \]
Given that the percent error is 0.75% and the actual value (temperature) is 16 degrees Celsius, we can substitute these values into the formula:
\[ \text{Absolute Error} = \left(\frac{0.75}{100}\right) \times 16 \]
Calculating this gives:
\[ \text{Absolute Error} = 0.0075 \times 16 = 0.12 \]
Therefore, we can report the temperature of the sample as:
\[ 16 \pm 0.12 \]
The correct response is:
16±0.12
