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, 488488 were in favor, 402402 were opposed, and 119119 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 119119 subjects who said that they were unsure, and use a 0.100.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.50.5. What does the result suggest about the politician's claim? This is the null hypothesis Upper H 0H0: pequals=0.50.5 Upper H 1H1: pnot equals≠0.5 Identify the test statistic for this hypothesis test. P value?
