Hoping to learn how to control crop damage by a certain species of beetle, a researcher plans to test two different H pesticides in small plots of corn. Afew days after application of the chemicals, the researcher will check the number of beetle larvae found on each plant. The researcher wants to know whether either pesticide works and whether there is a signicant difference in effectiveness between them. Design an appropriate experiment. E identify the number of factors, the level of each factor, and the number of treatments. Choose the correct answer below and ll in the answer boxes to complete your choice. 't A- There is one factor (beetle larvae) at D levels, with D total treatments. (Type whole numbers.) - There are two factors (pesticide and beetle larvae), at L} and f , l levels respectively, with a total treatments. (Type whole numbers.) - There is one factor (pesticide) at [J levels, with l J total treatments. (Type whole numbers.) What is the response variable? O A. Type of pesticide used 0 B. Amount of pesticide used 0 C. Number of beetle larvae O D. Presence of beetle larvae Apply each treatment to the same number of plots of land. To control the experiment, the plots should be as similar as possible; otherwise, use blocking to group plots with similar characteristics. After a given period of time, measure the response variable and compare the results. What characteristics could be used for blocking? Select all that apply. 1:] A. Size ofeld E] B. Water 1:] C. Type of pesticide used I: D. Presence of beetle larvae [:1 E. Proximity to other plants 1:] F. Sunlight
