A simple random sample of 27 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 0.20 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 0.30 mg, which is the standard deviation for unfiltered king- size cigarettes. Complete parts a through d. A. What are the null and alternative hypotheses? b. Find the test statistic x^2 x^2 =______ c. Find the p value of the test statistic p- value ____
