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, 484 were in favor, 399 were opposed, and 121 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 121 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? B. $H_o: p = 0.5$ $H_1: p < 0.5$ C. $H_o: p \neq 0.5$ $H_1: p = 0.5$ D. $H_o: p = 0.5$ $H_1: p \neq 0.5$ Identify the test statistic for this hypothesis test The test statistic for this hypothesis test is (Round to two decimal places as needed)

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, 484 were in favor, 403 were opposed, and 123 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 123 subjects who said that they were unsure, and use a 0.01 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? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p ≠ 0.5 H1: p = 0.5 B. H0: p = 0.5 H1: p > 0.5 C. H0: p = 0.5 H1: p ≠ 0.5 D. H0: p = 0.5 H1: p < 0.5
