Question

A pesticide manufacturer claims that their new product will kill 30% more bedbugs than the current leading brand of pesticide treatment. To verify this claim, an experiment was performed. The first population of bedbugs of the same species is grown in a captive environment without any pesticide for a 20 week period. The second population of bedbugs of the same species as population one is grown in the same type of environment for the same 20 week period but is given 25 grams of the new pesticide. The third population of bedbugs of the same species as population one and two is grown in the same type of environment for the same 20 week period but is given 25 grams of the current leading brand of pesticide. All three populations of bedbugs experienced the same weather conditions, given the same amount of water, and given the same amount of food. At the end of the 20 week period, the scientist measured the number of dead bedbugs in each population. The data collected was then sent to an independent research company to verify the results. What is the independent variable in Sample Experiment #1? a Amounts of pesticide b Type of pesticide. c Food and water. d Number of dead bedbugs
