Which of the following statements demonstrates the correct wording for a null hypothesis?
  1. Women who consume large amounts of dietary fiber have the same rates of cardiovascular disease as women who consume lesser amounts of dietary fiber.
  2. Women who consume large amounts of dietary fiber have lower rates of cardiovascular disease than women who consume lesser amounts of dietary fiber.
  3. Dietary fiber intake does not affect rates of cardiovascular disease in women.
  4. Women should eat more dietary fiber to lower their risk of cardiovascular disease.
Explanation
Answer: A - The correct wording for a null hypothesis is, “Women who eat large amounts of dietary fiber have the same rates of cardiovascular disease as women who consume lesser amounts of dietary fiber.” This statement is correct because the null hypothesis states there is no relationship between two variables, and that any observed difference results from chance. In research the null hypothesis is used to create an alternative hypothesis which states that a relationship between the two variables does exist.
