A simple random sample of 29 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 0.16 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 0.20 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? B. Ho: 0 >0.20 mg Hy: 050.20 mg A. Ho: 070.20 mg H1:0 = 0.20 mg C. Ho: a = 0.20 mg H4:0*0.20 mg D. Họ: 3 = 0.20 mg H4:0<0.20 mg b. Find the test statistic. x = (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 0.20 mg.
