Problem 2: Smoothing Univariate Data (25 points) Suppose you are given the data to analyze that includes a single attribute age. Following are the age values in unsorted order, 22 46 13 70 35 20 19 45 25 40 15 22 33 35 33 30 35 35 21 36 52 25 20 25 16 16 25 17 (a) Use smoothing by bin means to smooth these data, using a bin depth of 4. Illustrate your steps. (b) Use smoothing by bin boundaries to smooth these data, using a bin depth of 4. Illustrate your steps. (c) How might you determine the outliers in the data? *it is not necessary for you to use R for solving the above problem. Type your answer in a file
