A veterinarian was studying suspected causes of enteroliths, concretelike balls in the colons of horses. She suspected that a diet of mostly alfalfa could be a cause. In a study conducted at a veterinary research facility she examined the records of 62 horses with enteroliths (cases) and compared them with the records of 75 horses free of enteroliths (controls). To assess the conjecture that horses that are fed primarily alfalfa are more prone to getting enteroliths, she testedH₀:p_case-p_control = 0 vs.H_a:p_case-p_control > 0, wherep_case is the proportion of horses with enteroliths that are fed mostly alfalfa andp_control is the proportion of control horses mostly fed alfalfa. TheP-value for this test isp < 0.001. On the basis of an value of 0.05, she concluded that:

A)	it is likely that the proportion of horses with enteroliths that are fed primarily alfalfa is higher than the proportion of control horses primarily fed alfalfa.
B)	the null hypothesis should be rejected in favor of the alternative hypothesis at = .01.
C)	the probability of a type I error is 0.05.
D)	All of the above
