Consider the following two sample data sets. Set 1: 5 8 9 4 7 0 Set 2: 9 12 17 2 7 a. Calculate the coefficient of variation for each data set, b. Which data set has less consistency (or more variability)? a. The coefficient of variation for set 1 is %. (Round to one decimal place as needed.) The coefficient of variation for set 2 is %. (Round to one decimal place as needed.) b. Which data set has less consistency (or more variability )? Choose the correct answer below. O A. Data set 1 has less consistency (or more variability) because its coefficient of variation is less. O B. Data set 2 has less consistency (or more variability) because its coefficient of variation is greater. O C. Data set 2 has less consistency (or more variability) because its coefficient of variation is less. O D. Data set 1 has less consistency (or more variability) because its coefficient of variation is greater
