A study has been made to compare the nicotine contents of cigarettes and electronic cigarettes. A sample of measurements of nicotine content in cigarettes (Group 1) is obtained for comparison with another sample obtained from electronic cigarettes (Group 2). Dataset is available at nicotine content.csv ↓ Assume that the measurements for both groups follow a normal distribution and the populations' variances are equal. By the 95% confidence interval for the difference between the means of the first group and the second group. i.e., 1 - μ2, we can conclude that A: With 95% confidence, we have evidence to indicate that there is a difference between the amount of nicotine contents of cigarettes and electronic cigarettes. B: With 95% confidence, we have NO evidence to indicate that there is a difference between the amount of nicotine contents of cigarettes and electronic cigarettes. O A OB
