n an effort to determine whether a new type of fertilizer is more effective than the type currently in use, researchers took 5 two-acre plots of land scattered throughout the village. Each plot was divided into two equal-size subplots, one of which was treated with the current fertilizer and the other of which was treated with the new fertilizer. Wheat was planted, and the crop yields were measured given in the following table Plot 1 2 3 4 5 Current Fertilizer 56 45 69 57 60 New Fertilizer 49 66 61 58 75 Can we conclude at the 5% significance level that the new fertilizer is more effective than the current one?

A group of researchers measured how funny people rated a cartoon when they were in one of two groups: holding a pen in their teeth (forcing them to smile) or holding a pen in their lips (forcing them to frown). For this study, identify the independent variable and the dependent variable. Justify your response.
