Statistics
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, 481 were in favor, 404 were opposed, and 115 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 115 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? D. Ho:p=0.5 H4:p#0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is 2.59 (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is .01. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. O B. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. O C. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. O D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.
