Is the observed sample proportion unusual? Based on previous studies, researchers have that 6% of children are born with a gene that is linked to be a certain childhood disease. If the researchers test 950 newborns for the presence of this gene, would it be unlikely for them to find fewer than 25 children with the gene? Answer by calculting the appropirate z-score. Round to the nearest hundredth when necessary. a)No, z=-0.005 b)Yes, z=-4.41 c)No, z=-6.59 d)Yes, z=-6.59 e)No, z=-4.41 I've confused about choosing between yes or no.
