A measurement is given. Find the minimum and maximum possible measurements.
A nurse measures a newborn baby to be 22 in. long to the nearest in.
To find : the maximum and minimum possible measurements .
Answer to Problem 16P
Minimum measurement =19.5 in. and maximum measurement =20.5 in.
Explanation of Solution
Given information: A nurse measures a newborn baby to be 22 in. long to the nearest in.
Calculation:
The degree of accuracy is half a unit of measure.
The measurement was made to the nearest in. , so the greatest possible error is half of 1 in., that is 0.5 in.
Therefore,
Minimum measurement=(20-0.5) in. =19.5 in.
Maximum measurement=(20+0.5) in. =20.5 in.
