Extracted text: A simple random sample of 28 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? O A. Ho: o = 0.35 mg H,: o<0.35 mg="" b.="" ho:="" o="0.35" mg="" h,:="" o#0.35="" mg="" o="" c.="" ho:="" o=""> 0.35 mg H1: os0.35 mg OD. o+0.35 mg H1: 0 = 0.35 mg b. Find the test statistic. (Round to three decimal places as needed.)
