Assume that adults were randomly selected for a poll. They were asked if they"favor or oppose using federal tax dollars to fund medical research using stem cells obtained from humanembryos." Of thosepolled,481 were infavor,402 wereopposed, and123were unsure. A politician claims that peopledon't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the123 subjects who said that they wereunsure, and use a0.01

significance level to test the claim that the proportion of subjects who respond in favor is equal to0.5.

What does the result suggest about thepolitician's claim?
