A simple random sample of 30 filtered 100-mm cigarettes is obtained from a normally distributed population, and the tar
A simple random sample of 30 filtered 100-mm cigarettes is obtained from a normally distributed population, and the tar content of each cigarette is measured. The sample has a standard deviation of 0.22 mg. Use a 0.05 significance level to test the claim that the tar content of filtered 100-mm cigarettes has a standard deviation different from 0.35 mg, which is the standard deviation for unfiltered king-size cigarettes. Complete parts (a) through (d) below. a. What are the null and alternative hypotheses? OA. Ho: o 0.35 mg OB. Ho: Hạ : o # 0.35 mg 0.35 mg Hạ : a = 0.35 mg O C. Hoi o =0.35 mg OD. Ho: >0.35 mg Hạ: a<0.35 mg Hạ: os 0.35 mg b. Find the test statistic.. x² = (Round to three decimal places as needed.) c. Find the P-value of the test statistic. The P-value of the test statistic is. (Round to three decimal places as needed.) d. State the conclusion. Ho. There sufficient evidence to conclude that the tar content of filtered 100-mm cigarettes has a standard deviation different from 0.35 mg.
