he data below represent the nationwide highest yields a. rust consider the cata for one-year CUS. or one-year CDs and five-year CDs. The variance is One-Year Five-Year O (Round to five decimal places as needed.) CD CD 5.35 5.94 The standard deviation is . 5.30 5.90 (Round to four decimal places as needed.) 5.30 5.83 5.31 5.82 The range is 5.26 5.80 (Type an integer or a decimal. Do not round.) a. For one-year CDs and five-year CDs, separately compute the variance, The coefficient of variation is%. standard deviation, range, and (Round to four decimal places as needed.) coefficient of variation. b. Based on the results of (a). Now consider the data for five-ye\\ CDs. do one-year CDs or five-year CDs have more variation in the highest The variance is. yields offered? Explain. (Round to five decimal places as needed.) The standard deviation is (Round to four decimal places as needed.) The range is ]. (Type an integer or a decimal. Do not round.) The coefficient of variation is (Round to four decimal places as needed ) The range is (Type an integer or a decimal. Do not round.) The coefficient of variation is%. (Round to four decimal places as needed.) b. Choose the correct answer below. O A. Five-year CDs have more variation because they have a higher variance, standard deviation, range, and coefficient of variation. O B. The two investments have approximately the same variation since the difference in their standard deviations is less than 0.1. O C. One-year CDs have more variation because they have a lower variance, standard deviation, range, and coefficient of variation. O D. It cannot be determined
