A 'Health-Watch' group claims that a cigarette manufacturer's advertisement that its new low- tar cigarette "contains on average at most 3 milligrams of tar per cigarette" is misleading. The group believes that the level of tar per cigarette is higher. A careful analysis of a random sample of 25 cigarettes by the group yields an average of 3.19 milligrams of tar per cigarette, with a sample standard deviation of 0.39 milligrams. Assume the distribution of tar content in milligrams per cigarette is normal. What is the associated p-value of the test statistic for testing the group's claim?

A Health-Watch' group claims that a cigarette manufacturer's advertisement that its new low-
tar cigarette "contains on average at most 3 milligrams of tar per cigarette" is misleading. The
group believes that the level of tar per cigarette is higher. A careful analysis of a random
sample of 25 cigarettes by the group yields an average of 3.19 milligrams of tar per cigarette,
with a sample standard deviation of 0.39 milligrams. Assume the distribution of tar content in
milligrams per cigarette is normal. What is the associated p-value of the test statistic for testing
the group's claim?
