Heartburn Treatment
An ad for a new heartburn treatment says that it “reduces heartburn by 300 percent.” What does this mean?
A.It means that there is 3 times as much heartburn before using the treatment as there is after using it.
B.It means there is only seven-tenths as much heartburn after using the treatment because 300/1000 = 0.3, or three-tenths
C.It’s nonsense, because removing 100 percent of the heartburn already removes all of it.
D.It’s nonsense, because heartburn is a categorical variable, so percents don’t make sense
E.It’s nonsense because percents only make sense for counts, and amount of heartburn isn’t a count.
Well, removing 100% of the heartburn removes it all. So the answer is C, its nonsense!
