The western blot assay is a blood test for the presence of hiv. It has been found that this test sometimes gives false positive results for hiv. A medical researcher claims that the rate of false positives is 2%. A recent study of 400 randomly selected US blood donors who do not have hiv found that 2.5% received a false positive result. At a= 0.05 is there enough evidence to reject the researchers claim?
