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, critical value(s), 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 19.4 mg and a standard deviation of 3.45 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? hter What are the hypotheses? O A. Ho u= 21.1 mg H.µ<21.1 mg O B. Ho u=21.1 mg H,: 221.1 mg OC. Ho: H>21.1 mg H µ<21.1 mg O D. H,: p<21.1 mg H, u221.1 mg: Identify the test statistic. (Round to three decimal places as needed.) Identify the P-value.
