For conducting a two-tailed hypothesis test with a certain data set, using the smaller of n1minus1 and n2minus1 for the degrees of freedom results in dfequals11, and the corresponding critical values are tequalsplus or minus2.201. Using the formula for the exact degrees of freedom results in dfequals19.063, and the corresponding critical values are tequalsplus or minus2.093. How is using the critical values of tequalsplus or minus2.201 more "conservative" than using the critical values of plus or minus2.093?

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
