Problem Solving (Measures of Center and Variation)(20pts) 3. The circle graph shows the distribution of the ages of 200 students in a college Psychology I class. College Student Ages 20 yr: 14% 19 yr: 30% 21 yr. 20% 18 yr: 35% 37 yr. 1% a. Find the mean, median, and mode of the students' ages. b. Identify the outliers. How do the outliers affect the mean, median, and mode? c. Suppose all 200 students take the same Psychology II class exactly 1 year later. Draw a new circle graph that shows the distribution of the ages of this class and find the mean, median, and mode of the students' ages. Reflective question #3: Let's say you calculate the standard deviation of the data set for the first circle. Can the standard deviation be 0? Can the standard deviation be negative? Explain
