a survey reported the following results about gender, marital status and education of the readers of a particular publication. it reported that of the 1000 ppl surveyed 312 are male, 470 are married, 525 are college graduates, 42 are male college graduates, 147 are married college graduates, 86 are married males, and 25 are married male college graduates. can this info. be correct? why or why not?
This info can be correct. In this instance the designations are not mutually exclusive. Of 1,000 people 312 of them are male--that is the highest number. The overall highest number of married males can be 312 (number of males is lower than number married), and it states 86 are. That is ok. Of the 86 only 25 are married graduates. That is less than 86, so it checks out.
