Example 4
An experiment is performed to determine whether the average nicotine content of one kind of cigarette exceeds that of another kind by 0.20 milligram. If n1 = 50 cigarettes of the first kind had an average nicotine content of 1= 2.61 milligrams with a standard deviation of s1 = 0.12 milligram, whereas n2 = 40 cigarettes of the other kind had an average nicotine content of x2 = 2.38 milligrams with a standard deviation of s2 = 0.14 milligram, test the null hypothesis μ1 - μ2 = 0.20 against the alternative hypothesis μ1 - μ2 0.20 at the 0.05 level of significance. Base the decision on the P-value corresponding to the value of the appropriate test statistic.
