Answer 23

There's nothing whatsoever wrong with your data as you have typed them in.

This problem involves "contingency tables." If y ou have a reference on hand, such as a textbook, online learning materials, or access to Google, look that up if you need to. To me, three of the four given tables are clearly wrong. Before you look at them and try to decide which ones are wrong and which one is correct, best to look at any examples you've discovered through your research.

Answer 24

yes you are right, it is B

Answer 25

Corrrrrrrrrrect! :-) Mathmale.. also got a point.

Answer 26

Hint: Table A is incorrect because the header ("No sport" "No instrument") mixes two different things, like oil and water. The header MUST read either

"Sport" "No Sport" or "Instrument" "No instrument."

Answer 27

Curious...who rejected D and why?
