Joey and Ross designed an experiment to test the effectiveness of the newest acne cream on the market, Zit-B-Gone. Joey followed the manufacturer's directions for a total of 10 days. Each day Joey and Ross counted the number of blemishes on Joey's face and recorded the results. At the end of the 10 days, they created a line graph of their data. They concluded that Zit-B-Gone was not effective in removing blemishes. Janice, a representative from the company, sees their results and tells them, "Zit-B-Gone works just fine...Look at how your blemishes decreased in the first few days." How should Joey and Ross respond to Janice?



A) They should ignore the data after day 5 and agree with Janice.
B) They should restart the whole experiment and throw out all of the current data.
C) They should say that Zit B Gone was not effective because the blemishes reappeared.
D) They should agree with Janice and realize that they have looked at the data wrongly.
