Q:
# Plz show your work and answer quickly. I'll give brainliest!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.Yes, Jim made a good inference because most students at the rink were sixth graders.

Accepted Solution

A:

Hello there! :)

Jim only interviewed 5 students, all of which were at the same place.

So, 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.

If he asked students in multiple places or asked more people, it may have been a better inference.

The correct answer is "A".
