The data below represent the nationwide highest yields for one-year CDs and five-year CDs. a. First consider the data for one-year CDs. One-Year Five-Year The sample variance is CD CD (Round to five decimal places as needed.) 5.36 5.96 5.32 5.89 5.30 5.84 The sample standard deviation is 5.31 5.83 (Round to four decimal places as needed.) 5.25 5.79 The range is a. For one-year CDs and five-year CDs, (Type an integer or a decimal. Do not round.) separately compute the sample variance, sample standard deviation, The coefficient of variation is% range, and coefficient of variation. (Round to four decimal places as needed.) b. Based on the results of (a), do one-year CDs or five-year CDs have Now consider the data for five-year CDs. more variation in the highest yields offered? Explain. The sample variance is (Round to five decimal places as needed.) The sample standard deviation is (Round to four decimal places as needed.) The range is (Type an integer or a decimal. Do not round.)
