Imagine you are planning a study to determine if eating 1/2 teaspoon of cinnamon daily lowers blood pressure.  You have decided to use a Paired T-Test and 20 subjects.  Ten subjects will eat 1/2 teaspoon of cinnamon daily for two weeks and 10 will have their normal diets.  Blood pressure will be measured at the end of these two weeks.  Then the 10 on the cinnamon diet will go back to their regular diets and the 10 on the regular diets will switch to eating 1/2 teaspoon of cinnamon daily.  These subjects will continue this for two week and again their blood pressures will be measured. This is called a cross-over trial.  In the end, each subject will have two measurements of blood pressure, one on regular diet and one on the cinnamon diet. What is the null hypothesis of this Paired T-Test?  (please state this using a complete sentence).
