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 human embryos." Of those polled, 489 were in favor, 403 were opposed, and 125 were unsure. A politician claims that
people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 125 subjects who said that they were unsure, 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 the politician's claim?
