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, 487 were in favor, 402 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 0.10 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 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is __________ (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is _______ (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. A. Reject H0. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. B. RejectH0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. C. Fail to reject H0. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. D. Fail to reject H0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss. What does the result suggest about the politician's claim? A. the results suggests that the politician is wrong in claming that the responses are random guesses equivalent to a coin toss B, the results suggest that the politician is correct in claiming that the responses are guesses equivalent to a coin toss C. the results suggests that the polititicain is doing his best to accutatelty portray the feelings of the people D. the results are inconclusive about weather the politician is correct of not

Question

487

were in favor,

402

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

0.10

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.

H0:p≠0.5

H1:p=0.5

H0:p=0.5

H1:p<0.5

H0:p=0.5

H1:p>0.5

D.H0:p=0.5

H1:p≠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.)

Identify the P-value for this hypothesis test.

The P-value for this hypothesis test is

_______

(Round to three decimal places as needed.)

Identify the conclusion for this hypothesis test.

A. Reject H0. There is not sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

RejectH0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

Fail to reject H0. There is not

sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

Fail to reject H0. There is sufficient evidence to warrant rejection of the claim that the responses are equivalent to a coin toss.

What does the result suggest about the politician's claim?

A. the results suggests that the politician is wrong in claming that the responses are random guesses equivalent to a coin toss

B, the results suggest that the politician is correct in claiming that the responses are guesses equivalent to a coin toss

C. the results suggests that the polititicain is doing his best to accutatelty portray the feelings of the people
