This is the topic of design of experiment. RCBD = Randomized Complete Block Designs. Any help is greatly appreciated!

Extracted text: Problem 1 Paper Helicopter Experiment A researcher would like to investigate how long a paper “helicopter" can stay in the air, where the helicopter is dropped from a height of 2 meters. Here's how she make the paper helicopters (see the figure below for an example) to be used for the experiment. Leg Width: 5 cm Cut on Edotted Rotor line Length Rotor A Rotor B Body Length: 2 сm Fold on Body broken lines Leg Length Leg B Cut on dotted Leg A Leg C line Leg Width Source: https://blog.minitab.com/en/learning-design-of-experiments-with-paper- helicopters-and-minitab • Step 1: Cut the paper to a width of 5cm. (c) Think of a situation that the research would need to co ler a (d) If the researcher what to study what effects do leg length and width have on the flying time of heavy paper helicopters, which design is most appropriate for this situation? If the researcher want to have 5 replicates for each treatment combination, how many heavy paper helicopters does she need?
