Question

In a survey of 2284 adults, 735 say they believe in UFOs. Construct a 99% confidence interval or the population proportion of adults who believe in UFOs. A 99% confidence interval for the population proportion is (Round to three decimal places as needed.) Interpret your results. Choose the correct answer below. A. With 99% probability the population proportion of adults who do not believe in UFOs is between the endpoints of the given confidence interval. B. With 99% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval. C. The endpoints of the given confidence interval shows that 99% of adults believe in UFOs. D With 99% confidence, it can be said that the sample proportion of adults who believe in UFOs is between the endpoints of the given confidence interval. For the statement below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify which represents the claim. According to a recent survey, 31% of college students own a credit card. Write the claim as a mathematical statement. Choose the correct null and alternative hypotheses below. identify which is the claim. The alternative hypothesis H_a: p > 0.31 is the claim. The null hypothesis H_a: p = 0.31 is the claim. The null hypothesis H_a: p greaterthanorequalto0.31 is the claim. The alternative hypothesis H_a: = p notequalto 0.31 is the claim. The alternative hypothesis H_a: P 79: alpha = 0.10 Sample statistics: x = 82.1, s =3.6. n = 24 What are the null and alternative hypotheses? Choose the correct answer below. What is the value of the standardized test statistic? The standardized lost statistic is. (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value = (Round to three decimal places as needed) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. A. Fail to reject Hg. There is not enough evidence to support the claim. B. Reject Hg. There is not enough evidence to support the claim. C. Fail to reject Hg. There is enough evidence to support the claim. D. Reject Hg. There is enough evidence to support the claim.
