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,
490
were in​ favor,
396
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
0.10
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?
