A gardener is interested in seeing if sunlight and fertilizer type interact so that the effect of fertilizer type depends on the amount of sunlight that plants receive. The gardener randomly assigns half of the plants to be in sunlight and half the plants to be in shade. The gardener also randomly assigns half of the plants to receive the new fertilizer and half to receive an old fertilizer. After a month, the gardener measures plant height. 1 What hypothesis test would be most appropriate for answering this research question and why? 2 What are the independent and dependent variables (if any)? 3 How many levels do the independent variable(s) have?
