Consider an investor who, on January 1, 2019, purchases a TIPS bond with an original principal of $120,000, an 8 percent annual (or 4 percent semiannual) coupon rate, and 15 years to maturity. a. If the semiannual inflation rate during the first six months is 0.3 percent, calculate the principal amount used to determine the first coupon payment and the first coupon payment (paid on June 30, 2019). b. From your answer to part a, calculate the inflation-adjusted principal at the beginning of the second six months. c. Suppose that the semiannual inflation rate for the second six-month period is 1.2 percent. Calculate the inflation-adjusted principal at the end of the second six months (on December 31, 2019) and the coupon payment to the investor for the second six-month period. (For all requirements, round your answers to 2 decimal places. (e. g., 32.16)) a. Coupon payment b. Inflation-adjusted principal C. Inflation-adjusted principal at the end of the second six months Coupon payment

The hawthorne works was a large western electric factory with 45,000 employees. during the 1920s and 1930s, hawthorne works was the site of some well-known industrial studies. in one of the studies, researchers investigated the impact of different working conditions on worker productivity. prior to the start of the study, researchers secretly measured workers' productivity for several weeks. then researchers chose two workers, who then chose their own teams. the teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). for each of these changes in working conditions, the researchers measured the effect on productivity. for some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity.why did the researchers secretly measure the workers' productivity before creating the two treatment groups? a, to create similar treatment groups so that a cause-and-effect relationship could be establishedb, to draw conclusions about the productivity of all workers in the plant based on the test groupsc, to directly control for confounding variablesd, to provide a baseline for measuring worker productivity
