A researcher at a pharmaceutical company is interested in testing out the effects of a new drug, which he thinks will improve attention.  However, he also suspects that the effects of the drug interact with caffeine.  To test this, he tests six separate groups (n = 10, in each group), given either a drug, a placebo, or no drug, and either having consumed caffeine, or no caffeine.  Each performs an attention task.  He collects the following data.   drug placebo no drug Caffeine  x = 5  x = 10  x = 15  x2 = 210  x2 = 330  x2 = 415 No Caffeine  x = 20  x = 10  x = 6  x2 = 780  x2 = 345  x2 = 270 What is the F-value (F-obtained) for the interaction between drug and caffeine (AxB interaction)?
