1) Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. What was the initial observation? Identify the- Control Group, Independent Variable, and Dependent Variable. What should Homer's conclusion be?

2) Krusty was told that a certain itching powder was the newest best thing on the market, it even claims to cause 50% longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual product. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) was sprinkled with the Experimental itching powder. Subject A reported having itches for 30 minutes. Subject B reported to have itches for 45 minutes. Identify the- Control Group, Independent Variable, and Dependent Variable. Explain whether the data supports the advertisements claims about its products.
