The mean tar content of a simple random sample of 25 unfiltered king-size cigarettes is 21.6 mg, with a standard deviation of 4 mg. The mean tar content of a simple random sample of 25 filtered 100-mm cigarettes is 13.3 mg with a standard deviation of 4.1 The accompanying table shows the data. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Let population 1 be unfilter king-size cigarettes. Complete parts (a) through (c) below. E Click the icon to view the data. OC. Ho HHz OA. Ho H = P2 H > 2 OB. Ho H
