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 - 2, 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.
