b. Identify the test statistic for this hypothesis test.c. Identify the P-value for this hypothesis test. 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 cellsobtained from human embryos." Of those polled, 486 were in favor, 399 were opposed, and 123 were unsure. A politician claims that people don't really understand thestem 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, anduse a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5.

The result suggests that the politician is correct in claiming that the responses are random guesses equivalent to a coin toss.O B. The results are inconclusive about whether the politician is correct or not.O C. The result suggests that the politician is wrong in claiming that the responses are random guesses equivalent to a coin toss.O D.

The test is to check the claim that the proportion of subjects who respond in favour is 0.5. Suppose, p is the population proportion of subjects who respond in favour. Given that, 399 respond in favour out of 885.The hypothesis of the test is H0: p=0.5 against Ha:p≠0.5. The test statistics of the test is Z=np^-0.50.5×1-0.5~Normal(0,1)=np^-0.50.5×0.5n is the sample size,p^ is the sample proportion. b. Given that, n=885, p^=399885 The test statistics value is z0=np^-0.50.5×1-0.5=np^-0.50.5×0.5=885399885-0.50.25=-2.9245 Therefore, the test statistic value is z0 =-2.9245.c. The p-value of the test is p-value=2PZ≥z0=2 PZ≥2.9245=2 1-PZ<2.9245 =21-0.9983=2×0.0017=0.0034 Therefore, the p-value of the test is 0.0034.
