1. What does the null hypothesis say about the difference between two sample means? 2. Are the values of / and off of any special interest to typical consumers of research? 3. Suppose you read that ? = 2.000, of= 20, p > .05 for the difference between two means. Using conven- tional standards, should you conclude that the null hypothesis should be rejected? 4. Suppose you read that ? = 2.859, of = 40, p <.01 for the difference between two means. using conven- tional standards should you conclude that null hypothesis be rejected on basis of information in question means is statistically significant when a researcher uses large sample he or she likely to reject hy- pothesis than small size if found participants .41 p would value r>
