Student folklore holds that answer b is very often the correct one in conventional multiple-choice exams, where each question has five possible answers. To test whether this belief holds for certain instructor, the students plan to examine the next 20 multiple-choice questions asked by the instructor. a. Is the binomial approach the appropriate in this instance? In other words, would the binomial assumptions be reasonable in this situation?b. Assuming that only one answer to any question is regarded as correct, what is the natural null hypothesis to be tested?c. Should the research hypothesis one-sided or two-sided.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false. (you must enter t or f -- true and false will not work.) f equation editorequation editor 1. a plane and a line either intersect or are parallel t equation editorequation editor 2. two planes parallel to a third plane are parallel f equation editorequation editor 3. two lines either intersect or are parallel f equation editorequation editor 4. two planes orthogonal to a third plane are parallel f equation editorequation editor 5. two planes orthogonal to a line are parallel f equation editorequation editor 6. two planes either intersect or are parallel f equation editorequation editor 7. two lines orthogonal to a third line are parallel t equation editorequation editor 8. two lines parallel to a third line are parallel t equation editorequation editor 9. two planes parallel to a line are parallel f equation editorequation editor 10. two lines parallel to a plane are parallel f equation editorequation editor 11. two lines orthogonal to a plane are parallel
