Answer to Problem 2E

Tenth of a pound

Explanation of Solution

Given:The weight of a puppywould be measured to the nearest tenth of a pound or tenth of an ounce.

The degree of precision needed mainly depends on the purpose of that measurement. In this case, the weight of the puppy would have been measured to decide the kind of drugs to be given or to check the health condition of the puppy. And for that purpose, measurement to the nearest tenth of a pound will give an appropriate precision, because variation in the weight by tenth of a pound will not cause drastic changes in type of drugs to be given or health condition of the puppy.
