ume 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, 485485 were in favor, 396396 were opposed, and 123123 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 123123 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? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pgreater than>0.50.5 B. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pnot equals≠0.50.5 C. Upper H 0H0: pnot equals≠0.50.5 Upper H 1H1: pequals=0.50.5 D. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pless than<0.5
