Below are sample questions representative of the exercises included on this worksheet and related ALG2.32 Selecting Appropriate Precision for Approximations skill assessments:

Problem 1Difficulty: Mastery
A technician can report a calibration result as 2.34678 volts or 2.35 volts. If the sensor is accurate to the nearest hundredth volt, which report is best?
A2.34678 V because it has more digits.
B2.35 V because it matches the sensor's supported precision.
C2 V because decimals are unnecessary.
D2.350000 V because trailing zeros add accuracy.
Solution & Explanation:The reported value should match the sensor precision, so 2.35 V is the most defensible choice.
Problem 2Difficulty: Mastery
A room is measured as 8.52 m by 6.47 m. Which final area report best matches the measurement precision if the product is rounded only at the end?
A55.1244 m2
B55.12 m2
C55.1 m2
D60 m2
Solution & Explanation:The product is 55.1244 m2, and reporting to the nearest hundredth matches the hundredth-place measurements.
