Q. What is the greatest possible error for a measurement of 4 inches?____ inches
Determine precision: Determine the precision for the measurement of 4 inches.Since the measurement is given as a whole number without any decimal or fractional parts, the precision is to the nearest whole inch.Precision: 1 inch
Calculate error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision.Greatest possible error =2Precision=21 inch=0.5 inches
