Is there a difference in the yields of different types of investments? The accompanying data provide yields for a one-year certificate of deposit (CD) and a five-year CD for 25 banks. Complete parts a through c below. Click the icon to view the yields for one-year CDs and five-year CDs. a. Construct a 90% confidence interval estimate for the mean yield of one-year CDs. Sus (Type integers or decimals rounded to two decimal places as needed.) b. Construct a 90% confidence interval estimate for the mean yield of five-year CDs. Sus (Type integers or decimals rounded to two decimal places as needed.) c. Compare the results of (a) and (b). Choose the correct answer below. O A. One can be 90% confident that the mean yield of one-year CDs is less than the mean yield of five-year CDs. O B. One can be 90% confident that the mean yield of one-year CDs is the same as the mean yield of five-year CDs. O C. One can be 90% confident that the mean yield of one-year CDs is greater than the mean yield of five-year CDs. O D. The mean yield of five-year CDs is greater than the mean yield of one-year CDs.
