8. A cigarette manufacturer sent each of two laboratories presumably identical samples of tobacco. Each made five determinations of the nicotine content in milligrams as follows: sample 1: 24, 27, 26, 21 and 24 sample 2: 27, 28, 23, 31 and 26 (a) common variance.) Be sure to state the null and alternative hypothesis and to interpret the result. Use a = 0.05. Were the two laboratories measuring the same thing? (Assume normality and (Ъ) Compute a 95% confidence interval for the difference in two means.
