1B. In a slightly different experiment, the students were allowed to discuss their estimates with their immediate neighbors in the classroom before reporting their adjusted estimates to the professor. The mean estimate was found to be a bit worse than the estimate in the original experiment, but still better than the individual estimates. Is this system a complex system? (Apply the same reasoning as above.) 2. As a curious Suffolk student, you observed that some English professors tend to spend most of their class time to the left of the projector screen, while others prefer the right-hand side. - Propose 2-3 research questions that could be asked with respect to this observation. - Propose a testable hypothesis that would answer at least one of your questions. - Suggest a feasible experiment that would let you reject the hypothesis or, conversely, build extra confidence in it. What are your dependent and independent yariables? (List all of them.) What are the possible controlled variables? (Give a few examples.) - You ran your experiment, and it led to the rejection of the hypothesis. How can you weaken the hypothesis in the hope to make it acceptable? 3. Generate 100 real random numbers between 0 and 1 (inclusive) with =rand () either in Excel or in Google Sheets. Calculate the mean, standard deviation, and coefficient of variance of the numbers. Next, generate 100 whole random numbers between 0 and 1 (inclusive) with =randbetween(). Naturally, the only numbers that you'll get in the second experiment are 0s and 1s. Calculate the mean, standard deviation, and coefficient of variance of the numbers. Explain the difference andlor similarity between the results of both experiments. Do not submit the actual random numbers, but include a table of all six statistical results
