Identify the null and altemative hypothesesI test statistic. Pivalue, and state the final conclusion that addresses the original claim. A simple mndom sample cf25 ltered 100 mm cigarettes is obtained. and the tar content ol'each cigarette is measured. The sample has a mean of19.6 mg and a standard deviation of 3.31 mg. Use a 0.05 signicance level to tes1 the daim that the mean tar content of ltered 100 mm cigarettes is less than 21.1 mg, which is the mean for unltered king size cigarettes. What do the results suggest. ifanything, about the effectiveness of the lters? What are the hypotheses? OA. H01u=21.1mg OE. H01p21.1mg OD. Ho:p=21.1 mg H11u
