Question

HURRY PLEASEEEEE

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?


A. 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.


B. 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.


C. Yes, Jim made a good inference because 32 is the same proportion to the population as 1 to 5.


D. Yes, Jim made a good inference because most students at the rink were sixth graders.
