The side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) include problems involving peptic ulceration, renal function, and liver disease. In 1996, the American College of Rheumatology issued and disseminated guidelines recommending baseline tests when prescribing NSAIDs. A study was conducted to determine if physicians taking part in a national database of computerized medical records performed the recommended baseline tests when prescribing NSAIDs. The researchers classified physicians in the study into four categoriesthose practicing in internal medicine, family practice, academic family practice, and multispecialty groups. The researchers wish to provide sufficient evidence to conclude that the type of practice is associated with performance of baseline tests. Which of the following is true?

		The null hypothesis states the type of practice and performance of baseline tests are not associated.
		The alternative hypothesis states the type of practice and performance of baseline tests are not associated.
		The alternative hypothesis states the type of practice and performance of baseline tests are correlated.
		The null hypothesis states the type of practice and performance of baseline tests are related.
