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,485 were infavor,405 wereopposed, and120were 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 the120 subjects who said that they wereunsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about thepolitician's claim?

Identify the null and alternative hypotheses for this test.
