Question 3 Define the function coin_simulation_and_statistic, which, given a sample size and an array of model proportions (like the one you created in Q1), returns the number of heads in one simulation of flipping the coin under the model specified in model_proportions. Hint: Think about how you can use the function sample_proportions.
