Leslie Knope has asked her co-worker Tom to measure the mood of park-goers in her hometown on a scale of 1-7. Below is the data collected from the first 10 people (N = 10). Using these data, answer each of the following questions. Make sure to label you answers with the correct letter and show all work for your calculations (much as you did for your lab assignment), but you do not have to show your work twice! For example, if you already calculated the mean in one answer, you do not have to calculate it again for another answer. Remember, you will answer this question similarly to how you submitted your lab assignment, typing up all your mathematical steps. No specific symbols are required for your answer, but each step and the results of each step must be shown. Mood ratings (1-10): (2, 5, 5, 6, 4, 7, 5, 5, 7, 3} A) Find the mean, median, mode of the sample. B) Compute the variance statistic. C) Compute the standard deviation statistic.
