A scientist measured the pressure in a phloem tube in a willow plant stem. He repeated his measurements to obtain nine readings.
The percentage error of the mean phloem pressure in this phloem tube is calculated using this equation.
Percentage error = Uncertainty in measurement/mean x 100.
The uncertainty in measurement is half the range of the measured values.
Calculate the percentage error of the mean phloem pressure in this phloem tube.
