Answer:
D) 34.5 and 35.5
Explanation:
The choices for this question are
A) 27.5 and 32.5
B) 30 and 40
C) 32.5 and 37.5
D) 34.5 and 35.5
If the instrument measures in units of 5, then, the measure must be included in an interval.
In this case, we have the measure 35. Observe that choices C and D include the measure 35. However, choice C, from 32.5 to 37.5 as a wider range of measures which can imply a bigger error margin.
On the other hand, choice D, from 34.5 to 35.5 is the best choice to measure 35, because it has a least range of measures, where 35 is in the middle of such interval.
Therefore, the right answer is D.
