Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value,, and state the final conclusion that addresses the original claim. A simple random sample of 25 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. The sample has a mean of 18.6 mg and a standard deviation of 3.71 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes. What do the results suggest, if anything, abc the effectiveness of the filters? What are the hypotheses? O B. Ho: =21.1 mg H4: u2 21.1 mg O D. Ho: H=21.1 mg H: u<21.1 mg O A. Ho: H>21.1 mg H:H<21.1 mg OC. Ho: H<21.1 mg H4: u2 21.1 mg Identify the test statistic. t= (Round to three decimal places as needed.) Identify the P-value. The P-value is (Round to four decimal places as needed.) State the final conclusion that addresses the original claim. Choose the correct answer below. O A. Reject Hn.

Assume that a simple random sample has been selected from a nomally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A simple random sample of 25 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. The sample has a mean of 18.6 mg and a standard deviation of 3.71 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes. What do the results suggest, if anything, about the effectiveness of the filters? What are the hypotheses? O A. Ho: u> 21.1 mg H:µ<21.1 mg O B. Ho: =21.1 mg Η μ2 21.1 mg O C. Ho: H<21.1 mg O D.

O A. Reject Ho. There is sufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes O B. Reject Ho. There is insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. O C. Fail to reject Hn. There is sufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. O D. Fail to reject Hn. There insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. What do the results suggest, if anything, about the effectiveness of the filters? O A. The results suggest that the filters increase the tar content. O B. The results suggest that the filtered cigarettes have the same tar content as unfiltered king size cigarettes. O C. The results suggest that the filters are effective. O D. The results are inconclusive because the sample size is less than 30. O E. The results do not suggest that the filters are effective.
