Question
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,
395 were opposed, and 119 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 119 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?
