A sociologist is doing a study on journalists. He attends a journalism conference, where he randomly surveys 390 journalists about the kind of automobile they own. Of these journalists 137 said that they own a compact car. There are about 1,700 journalists at the conference. About what percent of these journalists owns a compact car?
if it’s referring to 137 out of 1700, divide 137 by 1700 and multiply by 100. same for the other, except you divide 137 by 390.
