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,

481

were in favor,

398

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?
