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?
No, Jim did not make a good inference because his sample is too small and may be biased because he only asked
students that were at the rink.
No, Jim did not make a good inference because his sample is too small and 32 is not in the same proportion to the
population as 1 to 5.
Yes, Jim made a good inference because 32 is the same proportion to the population as 1 to 5.
