When Jim surveyed 5 sixth-grade students at the community skating rink, he found that only 1 out of the 5 had completed the
science project. He knows there are about 160 sixth-grade students in his community, so he infers that around 32 students
have finished their science project. Is this a good inference?

yes its a good inference

Step-by-step explanation:

its a good inference because if you multiply 32 by 5 it makes 160 and sense its 1 of every 5 it should be one fifth you find one fifth by dividing the hole number by 5 and reverse it by multiplying it by 5.
