Question

When Jeremy surveyed thirty 7th-grade students at the community pool, he found that 2/15 had not read at least one book during July. He knows there are about 200 7th-grade students in his community, so he infers that about 40 of them did not read any books in July. Is that a good inference? Explain.

Answer 2
