Question
Can someone tell me what formula I should use?
The number of milligrams of tar in filtered and unfiltered cigarettes is being compared. The following cigarettes are pulled to be part of the samples:
Filtered: bunch of data
Unfiltered: bunch of data
The first question is create a confidence interval of the difference between the two types of cigarettes.
Thanks
