Question

A simple random sample of 25 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. 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 3.2 mg, which is the standard deviation for unfiltered king size cigarettes. Find the statistic and the critical value (or values).
