Researchers suspected that the ability to correctly estimate the size of an object using your hands with your eyes closed is related to whether you are blind or sighted. A group of statistics students is working on a problem in which they are to state the appropriate alternative hypothesis in terms of parameters. Which student states it correctly? Adam: The alternative says there's a relationship between size estimate and whether you're blind or not. Brittany: In terms of parameters, the alternative says the mean estimate for all blind people is different from the mean estimate for all sighted people. Carlos: I think it was a paired study design, so the alternative would say that the mean of differences, blind estimate minus sighted estimate, does not equal zero. Dominique: It can't be paired because some people are blind and a separate sample of people are sighted. The alternative says that the mean estimate for the sample of blind people is different from the mean for the sample of sighted people.
