You want to determine whether the amount of coffee that "coffee drinkers" consume on a weekly basis differs depending on whether the coffee drinker also smokes cigarettes. You seek 20 volunteers from your college campus to participate. Ten college students reported that they consume coffee but do not smoke cigarettes; these comprise the Coffee-Only group, or Group 1. Another ten college students reported that they consumed coffee and also smoked cigarettes; these comprise the Coffee + Cigarettes group, or Group 2. Then you ask them to monitor the frequency of 8 ounce cups of coffee they consumed over a seven day period. Which hypothesis test needs to be employed here, the two-sample dependent t test or the two-sample independent t test?
