the following volumes are delivered from the same syringe.
1.34 milliliters
1.32 milliliters
1.36 milliliters
1.35 milliliters
which of the following choices are the best way to describe the data set if the syringe is supposed to deliver 1.50 milliliters?

select the correct answer

not accurate, nor precise.

accurate, but not precise.

accurate and precise.

not accurate, but precise.

Explanation:

1. Define Accuracy and Precision:

• Accuracy refers to how close a measured value is to the true (target) value. Here, the target volume is 1.50 milliliters.
• Precision refers to how close the measured values are to each other (consistency of measurements).

1. Analyze Accuracy: The measured values (1.34, 1.32, 1.36, 1.35 mL) are all far from the target value of 1.50 mL. So, the measurements are not accurate.
2. Analyze Precision: The measured values are very close to each other (differences are within 0.04 mL). This shows high precision.

Thus, the data set is not accurate (not close to 1.50 mL) but is precise (values are consistent with each other).

Answer:

Not accurate, but precise.
